DA-871/872/971/972

Long studied the market dvd GPS 2din multiservice devices, watched a lot of different things, eventually bought Chinese A & V (PIONEER) DA-971 GPS
Reviews, general specifications, equipment, manufacturer's website:

I want to warn! All that I wrote in my review relates to my specific model and configuration. Because The Chinese are working on cheaper products, where it is necessary and not necessary, and the quality can float (different matrices can be set). Why am I, I got a tape recorder with the Sagm module, and so, it seemed to me, we show it less clearly than my NWD Mesada. See with your own eyes, the reviews are different, I tried to be objective. New tape recorders with good resolution, more "beautiful" have already appeared.Radio with GPS, 800x480 (General Topic)but with a price of about $ 500.
DA-872 is DA-971 only without navigation - GPS parts.

Replacing a new menu.
My review:

His matrix is ​​awesome! REVIEW ANGLES are huge - visible from any direction, bright, bright, the color rendition is excellent, the pixels are not visible, you look at the picture is fascinating ... compared to the others I have seen - just fantastic ...
GPS resolution 480x234,in the new version 800 * 480!I use IGO.
The resolution in DVD, DivX is excellent.
In GPS mode, radio, MP3 plays.
Bluetooth works fine, legible, clearly without echo. There is no list, you can listen to music through Bluetooth, there are buttons.But you can hear it very quietly, you have to increase the volume. Later I eliminated it.
MP3 remembers the last song, there is no random selection of the song.
The sound is normal, distortions due to overload occur later than in my previous device orion dvd-088. The high frequencies are bright, crisp, overly underlined, the middle is not enough, I still listen to the sound.As it turned out later, the measurement sound is mediocre, but later I found the cause and eliminated it.
Rearview camera, TV without antenna has not yet connected.
There are two wires to connect the buttons on the steering wheel (key), as it is not understood.Work, except on / off.
There are drawbacks - the radio makes a noise in movement and, as it were, floods the high frequencies, it is annoyingly scary, the sound floats in motion ... - by level, by high frequencies, + it makes noise (I have an active antenna, it is connected correctly). I suppose that it is not designed for an active antenna, I will remove the amplifier, see what and how. As it is now not satisfied, just horror - receiver "no."As it turned out, I did not correctly connect the power of the antenna amplifier. See the connection features.
It is impossible to enter the setup DVD - accordingly, the parameter settings cannot be changed, although in the instructions there is such a possibility on the Setup button it also “beeps”.
The sound level in the receiver is too high, when switching from other sources it is necessary to make it quieter.Later eliminated.
When choosing, watching it, I thought it was the same Mr., but like what I saw everywhere on the wholesale market - 7 km (AVH-819, etc.), but when I bought
I was pleasantly surprised.

Became as native, as created for her, here are the pictures of the set, the slits are not visible. The muzzle does not climbs, it looks great, but I had to tinker for the manufacture of the ears and trim the bottom 4-5mm. Machine Hyundai Matrix. For a year of operation there was no damage. According to reviews, marriage is not enough.
Changed the menu to a new, stylish.
After completion of the soldering iron, eliminated all the flaws and got the receiver that he wanted.
After repeated fights, every time I was surprised at the high level of design, good quality: soldering, iron, assembly.
If you make improvements - it turns out a wonderful tape recorder, with characteristics and sound quality like that of famous brands, for ridiculous money!

OverviewGhost140:

First, the good:
1. Sound pleased, contrary to expectation.
2. Radio - test, (it works stably !!!) although I do not use it.
3.iGo 8.3 and Navitel 3.2.6 (put it myself, + last cards) - offset (conditional)
5. The mechanic works.
6. Uh ... well, that's all.
Now about the sad:
1. Matrix for C grade, and a little. Colors are far from reality (there is no black at all), photo / video stomps vertically by 10-15 percent !!! Even if you slip the perfect size (480x272) picture. Apparently laid down "STILL", programmatically or ironically? .. hz To get a circle on the screen, you need an ellipse stretched vertically. Those. It’s impossible to achieve a normal photo / video geometry, which is not at all good.
2. In navigation problems with geometry. The circle is not a circle, the square is not a square (test 5 prog). Touch in Navi ... well, I do not know, apparently you need to get used to it. Prots do not do well, even on medium map details (dragging a card with your finger is problematic).
3.When disc ejection, switch. on the radio, and here you can "get" to repair / replace glasses and eardrums. The sound of the radio, as already noted here, is too high, but I didn’t assume that it was SO MUCH.
4. Autorun of the last application from the main menu is quite annoying. Disable apparently impossible. (not critical)
5. The remote control is left-handed, a different one is indicated in the book. (As far as I understood, everyone has it)
6.When installed on regular brackets, the device is not misplaced. (Camry ACV30) Drill the brackets \ sharpen \ saw.
And finally, the last two shoals, through which the device can be labeled "CHINESE DISAPTERY" on the device
7. The inaccessibility of sound settings, and in particular the equalizer, during playback. Unforgivable cant.
8. The device has a CUSTOMED front. Vertical is higher than the standard by 5-6 mm. Therefore, the transition frame (if provided) will have to be “collective-farm” with a file!, Which is completely unacceptable. And even impossible on some cars.
TV and the camera has not yet connected.
I gave 11600r + 1130r-shipment. Overpaid. 7-8 thousand him the price in the market day. Given the functionality and navigation.
In operation on the car for 3 days. Correct if something is wrong.
Request to the respected members of the forum to unsubscribe under items 7 and 8. Who won how? (If he won)
Thanks to all.
Dinah:With geometry really crap, the study showed that the firmware thinks that it has a 4: 3 matrix, and in fact 16: 9, apparently the Chinese did not bother much about this, some problems were fixed, we are working on others

The review of the new version with the new screen resolution 800 * 480 in GPS from Brucekr:

We arrived 971 with a new screen 800 * 480. Visually, multimedia is much more beautiful, everything is dull in navigation, as if the contrast is overwhelmed. And the quality of the screen at 800 * 480 doesn’t pull at all. Adjustments don't save much.
The menu service comes, but the FM / AM gain does not work. The rest is all on the pictures:

A small review from me, because It was not possible to use it:

• Fixed a bug in switching voice commands GPS;
• the difference between the receiver's loudness levels and other sound sources was eliminated (I think how they implemented, it’s necessary to redo or collective farm something, everything is simple, an individual volume control that remembers the receiver’s loudness level was implemented in the receiver software.
� most importantly - the sound was goodbecause instead of the “basement” 7313 chips, they began to put something more decent: PTC PT7313E, can they read the forum? (I tried earlier versions of PTC - there was no quality!), if you have PT7313E, then you do not need to change it to TDA7313D. Measurements have shown that it does not spoil the sound PT7313E!

• remembers the last played track;
• added support for ipod in the menu, but how to connect is not clear.
Main disadvantages remained:
• mediocre receiver sensitivity;
• swimming receiver sound! Already there is a solution - we get add. Stereo decoder fee, details in a personal or ICq: 417635539
I did not dig deeper.

Treatise on SD cards

Some SD are not readable, formatting does not help, can be cured by sticking a piece of paper tape on the card. The card is slightly thickened and tightly pressed against the contacts.
In the radio two SD readers: Multimedia and GPS.
In multimedia, in older versions of the firmware (with the Pioneer logo) there were simple SD cards up to 4Gb, in the new multimedia version (CAR DVD, green stereo, in the header) the SDHC standard card allows up to 32Gb.
In gpsThe SDHC card module works, that is, the standard allows up to 32Gb ..
8 gigs in all holes works. But 16 is nowhere to be seen!
According to other data, 16Gb is coming.
Another cant. Listen to the flash drive (16Gb). Off mafon On - the flash drive does not see until you plug it and stick it again.
8 gig - no problem. (stereo white)

Troubleshooting - improvements DA-971:

Beginners do not even have to try. SLEEP, remember about grounding, statics, etc., at your own peril and risk: nono :!
The subtleties of disassembly - it is better to disassemble with the inserted cd disc. Do not forget to open locks on the trains. Do not break them, they do not like it. From the "sandwich" of the screen, the touch panel and the "farthing on the floor" will fall out, it is better not to disassemble the screen.
Leveling the volume - muting the receiver (no need for new versions):

We install 3.3kOhm resistors, as practice has shown better to put,2.2kOhm SMD size 0603 - turned divider, before soldering, clean the varnish, chew the earth.
Added laterYou can not serve the land, and place them at an angle of 90⁰how didSpa_m, :

Leveling the volume - increase the bluetooth volume:
Remove 10k ohm resistors in the OS OOS replace with 33k ohm SMD frame size 0402 or 0603:

it is necessary to solder jewelry, only to those who have a thin soldering iron and can solder well.
Significant improvement in sound quality - replacing the 7313 volume and balance control chip. (No need for new versions)
If you have a PT7313E, you do not need to change it to TDA7313D. Measurements have shown that it does not spoil the sound PT7313E!
We only buy STMicroelectronics TDA7313ND firms in the SO28 package and change the unknown Chinese fake 7313 to the TDA7313ND.
We get a new high-quality sound, the radio tape recorder is significantly transformed:
Sound before rework:andafter replacing with TDA7313ND
Remove USB from GPS module

The colors of the cable may be different, USB marking is on the back of the board:
(when you open it you will see), regardless of the GPS module, the conclusions are signed on the mother's connector:

among them, the 4th are responsible for USB: USB-5v, DN (D-), DP (D +), UGND find the match with "famale"http://ru.wikipedia.org/wiki/USBunsolder and everything is ok. The USB cable is better to use shielded with filters (barrels), I made a ring from the screen braid and through the washer under the screw of the mother for reliability.
I do not recommend loading USB input - use USB HUB with external power.
USB multimedia part
In order not to dangle the lace from the muzzle, it is soldered to the connector JP1, option from aleks576:
And from EVTEEV2007:

Laces in parallel do not use!
Finalization of the input circuit of the receiver
The bottom line is that the receiver input circuits are tuned to the middle of the band: the Soviet VHF band is 65-73 MHz + FM 88-108MHz is 87 MHz. You can reconfigure the middle 88-108MHz is 98 MHz, it is done by replacing 2 capacitors, it costs less than $ 1. But I left it for a snack. They are sold in babins, in ribbons of hundreds of thousands of pieces, but you can find 10 pieces of retail. Buy it is necessary ceramic capacitors: SMD size 0603 ratings: 18pF (picofarad) - 2 pcs. We sell them at least 10 pieces at a price of $ 0.2. - $ 0.3 a dozen. Change C61, C62, near the receiver. And on the receiver I put a small radiator - just in case. The saved parts should be kept and not be confused, so that there is an opportunity to return if you do not like the alteration. From practice it gives an increase in the reception, somewhere in two times. This is all that can be squeezed out of this.
GPS voice prompts while playing mp3, radio, etc. (in new versions it works without revision):
Two options, simple fromSpa_m, , by installing two wires, and more complicated from me.
First option from Spa_m, Mixes the sound of GPS prompts into the front speakers to an existing sound source.
As practice has shown, resistors are not needed!
The second option: it mutes the source (receiver, mp3, etc.) and switches to GPS, then returns.
Scheme
The transistors are practically any n-p-n current of at least 100mA, EC voltage is not less than 20V, I had MBT3904LT1.
Diode do not know, put that was :)))
Any relays to the appropriate voltage and contacts, I had these in stock.
Capacitors C1, C2 are C319, C320 removed from the motherboard.
Connection points to the motherboard

The resistor is removed.
Divorced, etched board - handmade: D
Finished board - for testing.

Replacing the UM TDA7388 on tda7560:
Changed, there is no significant difference. According to the measurements, the characteristics of the microcircuits are absolutely the same.
Comparison Vol.20
Overload Vol.35
Mono mode, instead of speakers resistance 3.9 Ohms, temperature +25⁰With BP auto battery: D
Fuss for replacing a lot, IMHO is not worth it.
It seems, subjectively, the sound has become tougher, IMHO the damping properties of the TDA7560 are better, the sound is an amateur - but this is all "seemed".
Elimination of the "sagging" of the voltage output AMR - power antenna amplifier, refinement of the Spa_m,
The 331 (501) resistor does not cross over, but it is better to install a self-disconnecting fuse for 100-200mA 14v, otherwise the stabilizer may burn out due to the closure of the AMP output.
Output of the line output of the rear channels for the power amplifier

Find a wire with two "tulips", solder the central conductors to LR and RR, the screen (braid) to the "screen" or to any point where the "case" (-) is better closer to the chip, so that there is less unshielded wire. Do not output LF and RF, since they are on the wiring harness. Line out

VERY IMPORTANT ! What should be avoided so as not to "kill" your device.
We have two relatively independent multimedia devices and GPS, two types of versions, two types of firmware: multimedia (Sunplus chip, right SD slot, DVD, CD) 720x480 ttrom.bin firmware and the second (ARM9 chip, samsung) GPS 480x234 or 800x480, left SD slot. Each has its own firmware, drawings, etc.
DVD part firmware for DA-971:

I strongly do not recommend, without needing, flashing the DVD part, there were two cases of failure, due to improper flashing, the 1st one pulled out the USB flash drive during the firmware, the 2nd one is unknown. To flip the multimedia part, insert the ttrom.bin firmware into the right SD slot. When flashing, do not turn off the radio tape recorder, do not remove the SD until turn off / on. Use firmware from "trusted publishers". Be careful. At one's own risk.

If there is a wish and those who do not have hints in GPS can help with fishing the new firmware of the DVD part from the manufacturer. You can contact the manufacturer via MSN: [email protected] and [email protected] Service Center, so to speak, 89099171853. The manufacturer, regarding the firmware, was told to contact representatives in Moscow, here are the contact details of tel.89260173805 tel.89057622362 "
There is a representative office in Moscow, they work there as usual for the Chinasians. Their Email [email protected] can only attack them in English. If the mafon is not bought from them, then they send it to where it took it.

FIRMWARE ONLY FOR DA-971, do not apply to others! Firmware for new version of models 800x4800805E There is! Apply in a personal or ICQ: 417635539. The following are not suitable for "800x480"!

Flashing experience

Firmware, dump, NandFlash GPS parts:

At the moment, it is known to use two types of GPS modules, two different manufacturers SACGM and MESADA NWD, respectively, with different firmware. In addition, there are different versions of hardware from the same manufacturer (NVD v6 ... v7).The module with a resolution of 800 * 480 "wasn’t twisted in the hands"; no firmware was seen; this is a new platform:

Photo review DA-974 from aleks576,

Reviews, those who put:

ProStoyIrk
_dimond

Connection Features:

1. ACC and + 12v The head unit took the main power from the ACC, and the constant +12 was used to "store settings." In the DA-971, the opposite is true and the wire is constant eg. + 12v is not suitable because I have it thin. I took a wire cross-section of 2.5-3 mm2 and, without fail, through a 15A fuse, I connected it to a permanent 12V ignition switch.
2. Convenience when I set the pandora 1870i alarm, the trunk channel turned on ACC and + 12V in parallel, and programmed this channel to turn on when the lock is turned and off when the alarm is set.
Thus, it is very convenient, I took out the keys of the radio tape recorder, it turned on the alarm, turned off, came, turned the key on, I had to turn it on - I turned on the remote with the remote control. In other signalka this is also possible. Recommend!
3. Output AMP and ANT , to power the antenna amplifier, you can not use, connect to the ACC through the protective fuse 1A. AMP does not give the desired current and power drops to 3 volts (but after the internal refinement described above, the AMP output can be used to power the antenna amplifier), ANT serves to extend the mechanical antenna, it works pulsed.
4. Outputs key +, key -, used to connect the control buttons on the steering wheel. In order to avoid damage, do not apply 12v to these inputs. . key + output + 5v to resistive divider, key- input from resistive divider (ADC input), black - common, body. Those. On "key -", depending on the button press, there should be a different voltage from 0 .... to 5v, i.e. each button press will correspond to its own voltage. But between the button voltages, there should be an interval of at least 0.5V.
After connecting the buttons, go to the menu and train. On / off button does not work.
CAN is not and is not supported.
A very necessary thing in terms of security and very convenient, the radio station clicks on the circle Fm1-Fm2-Fm3-Fm1, etc. Tracks toggles in navigation mode.

Known bugs. Possible malfunctions and methods of elimination:

Here is the telephone representation in Moscow. Service center 89099171853 as it were. The manufacturer, regarding the firmware, was told to contact representatives in Moscow. Just write in English. If the mafon is not bought from them, then they send it to where it took it.Somebody finish them, you need firmware for the motherboard control processor - m3030rfcpgp, flashing with the programmer. We didn’t run through it: (She has to solve the problem with hints in GPS and extension of mech antenna. It’s far and expensive to me from Odessa.
Known bugs:

1. The lack of voice prompts GPS (fixed in the new version) ( (ambush, turns) while listening to the radio, MP3. In new versions eliminated.
When you first turn on hints there, with subsequent no. IMHO existing flashing is not treated - need specific firmware for the motherboard control processor - m3030rfcpgp, flashing programmer.
Technical details:

Regarding the prompts, the 3rd processor participates in this, in a simplified way: percents. SUNPLUS sphe8202tqc in the DVD module (with its firmware), controls the multimedia part, resolves prompts, gives the go-ahead to the processor that controls the m3030rfcpgp motherboard (with its firmware) to receive a signal from GPS, GPS module ARM ...... ( firmware) and registry settings, through the wire AUD-SW (13pin) of the same connector, reports m3030rfcpgp, low signal level, that now I will say something! What the processor that controls the m3030rfcpgp motherboard urgently uses the I2C bus to switch the inputs of the 7313 and 74HC4052N chips to receive sound from the GPS, then, after the end of the signal - switching to high level AUD-SW (13pin), the sound is switched to the original source.
So, there is an error in the software (I even know which one: translation of the port from the input to the output), which leads to the lack of prompts in the firmware (in memory of U2 atmel 24c16n) percent. m3030rfcpgp. Flashing the multimedia part (SUNPLUS sphe8202tqСЃ) does not lead to the absence of GPS prompts, flashing the GPS module also should not lead to the lack of prompts if it software supports AUD-SW (13pin) signal transmission.

Torment the manufacturer of MSN: [email protected] Service Center 89099171853. As a way to eliminate hardware refinement, two options, the installation of two resistors or the addition of email. scheme is shown here in the "modifications".
2. High receiver volume - hardware revision, shown here above.
3. Low audibility of the interlocutor on bluetooth - hardware revision, shown here above.
4. Mediocre sound - hardware revision, replacement of the chip, is shown here above.
5. Navigation does not save program settings. (Navitel, etc.) - for PNA, to save the settings, a script is written using MortScript.exe with the help of this program in the navigator.mscr file you can see where to save the settings. At the same time, the navigation prog should be run by the file navigator.exe, not Navitel.exe, i.e. I summarize in the directory with the program should be present these files.
6. Spa_m (Here are possible options, describing how the glitch manifested itself in me) We listen to music from USB (4Gb), watch GPS, and then a phone call. We speak on the blue tooth. We put down the phone. We see the GPS on the screen, the sound does not turn on from USB. We switch to the media, we see the menu of the blue tooth, we try to get out of it - but we can't: smile_good.gif. It is treated on-off, but when they call for a lot of times for the trip, they are very annoying. by
7. There is no automatic dimming of the screen at night (when turning on the dimensions).
8. During DVD, USB, SD playback, the screen cannot be dimmed (receiver can).
9. In old firmware, the ANT output runs for the first time. Then the signal for the extension, the movement of the antenna does not give. I do not know how in the new ones. The reason is similar to claim 1 and the solution is that you need a specific firmware for the motherboard control processor - m3030rfcpgp. Hammer the manufacturer!
10. Spa_m : Plays Disc. Watching GPS. Turn off the mafon. Turn on. GPS loaded, the disk did not even spin. Switch to mafon mode. Click on the radio. Enjoy the glitch. Being treated off-on. Or turn off from CD mode.
11. Lack of RDS , the part of the radio tape recorder comes with RDS, the part without it, in the service menu such a function is enabled programmatically. For its operation, it is necessary for the receiver IC to support it or must be an RDS controller.
I have near the receiver IC, there is an empty, unsoldered place for the controller, as I assume for RDS. There are cases of stuttering sound with RDS turned on.
12. Geometry , with the geometry really crap, the study showed that the multimedia firmware thinks that it has a 4: 3 matrix, but in fact 16: 9, apparently the Chinese did not bother much about this because not much striking. We are working on it.
13. Contrast if the picture contrast in the menu is very bright or very dark, in the menu service we change the first parameter, set it up as you like.

Possible malfunctions and methods of elimination:

1. Redness of the screen, only in GPS mode The reason is that the jumper is not soldered on the GPS module, which sets the screen modes.
2. Does not give the disc To give it was necessary to knock on the radio tape recorder - the reason for the wire was pressed against the CD / DVD carriage, inside the radio tape recorder.
3. Poor radio reception, “float tone” stations - may not work regular antenna amplifier. One of the reasons is that the antenna amplifier is connected to the output of the AMP radio tape recorder, it does not give the required current and power drops to 3 volts, thus the antenna amplifier does not work (after the internal refinement described above, the AMP output can be used). Output AMP and ANT, to power the antenna amplifier, can not be used, connect to the ACC through the protective fuse 1A.
For some receivers, the antenna is powered by the center wire (as in TV amplifiers).
Not always the power supply solves the problem with the reception.Let's define the terms - “bad” reception is the swimming of the tone (as if the high frequencies are being removed), as if someone is turning the tone knob here and there. I studied this question along and across: in all modern receivers, methods of dealing with interference are laid. If earlier we heard hissing, now for the fight with noise (in our case as well as in other modern radio tape recorders) the high-pass filter is turned on and the degree of stereo decoding decreases. The idea may have been good, but the implementation of it leads to an unpleasant sound effect!
What to do? How to get rid? Disable them is not possible, because They are inside the chip. I suppose that it is possible to make it programmatically, but there is no such function and access to the software, too.
What do we have a radio with good functionality, at a good price, but with such a disadvantage! : o
But the solution is, it is not simple. Studying the chip of our receiver, I found in it the output of an unperformed signal, before the filters. I developed my own stereo decoder (separate board) in which these filters were turned off, sent an uncorrected signal to it and returned the left and right channels to the tape recorder. The finished stereo decoder card is not sold on the radio market. This is my development - know-how. The cap is not described.
I will say one thing, I received, not the first time, excellent stereo decoding, with no distortion, crystal clear sound! Nothing floats, I hear with what quality each station is broadcasting, who indulges in low-quality mp3, etc. In general, the sound of the receiver has become studio, I can demonstrate in Odessa.
Fees can be obtained from me, please contact in a personal or ICQ: 417635539.
It is not difficult to install it: two power wires, an input and two outputs, that's all. No larger than a matchbox, self-adhesive, double-sided tape.
4. Killed by flashing DVD module chik777 : .... I defeated the DVD module I killed while flashing ... I spent a long time trying to flash through the JTAG cord, but I didn’t manage to do anything with the computer. The decision was made by flashing a direct SPI Flash ..... We have this T16-75HIP ---------- 8 foot below the processor. Vypayal connected to the programmer and flooded ..... put back and all OKKKKKK.
5. The touchpad does not work. There have already been two cases, the touchpad ceases to work both in GPS and in multimedia - the cable is peeled off from the glass, we better carry it to the workshop or we glue ourselves.
6. Out of Memory in IGO, from 4pna, if anyone encountered the problem of IGO 8 operation, namely, “The program crashes with an Out of Memory error ?!”, the solution is this way: remove all in the data.zip and branding.zip files Unnecessary screen extensions left only its 480x234. these files become smaller in size and everything should work.

There was a solution - the elimination of the "float" sound receiver! Now a clean studio sound receiver for you!
Details here:

The reason is that in the new receivers (and in the TEF6624T) there are two filters, one reduces the high frequencies, and the second decreases the stereo decoding and they are connected when the signal is weak. In the old receivers this was not the case. when a weak signal, you heard only psh-shi-k ... and that's it.
And now clever uncles, in new microcircuits masks this psh-and-k, including filters. You hear it as a floating sound, disgusting, disgusting, annoying!
The microcircuit itself receives weakly; the external amplifiers do not solve the problem. Hardware can not disable the filters. But the solution was found! I found a signal in the receiver to a stereo decoder. I made an external, my own stereo decoder, in which these filters are disabled, and from it I fed back to the radio tape recorder the L, R channel.
As a result, he received high sound quality, studio sound, he heard the stations broadcasting in different ways and the most important thing is NO FLOATING sound.
At the request of colleagues, I started to make stereo decoder boards.
I will say one thing, I received, not the first time, great stereo sound, with no distortion, crystal clear! I tried different chips.
In my THD, Total Harmonic Distortion = 0.02%. And in native 1%!
Channel Separation 30 ... 45dB, in native 26 .... 40dB
pilot suppression 55 ... 70 dB, in the native 30..40dB
Install the board at the nearest radio workshop. It is connected by 5 wires: two power supply, 1 input, two R, L outputs.

meowmeowmeow,
What model?

[olzheka]

Good day. Help identify the 2din model. Need a DVD module firmware for this device, because the clumsy Russian in the player is very annoying. Thank you in advance

Guys, good time of day. Tell me how to determine the model of car radio, da-872 or da-971, which one can? When enabled, writes on a blue background cardvd.

[lpavel2004]

Good time! The device DA971-apparently, after problems with the power when the device was turned on, the media point failed to work in multimedia mode, it works in zhps. Tell me, what can I do (if I don’t carry it to the workshop)? Reflash WinCe? :)

[Drunj2011]

Hello. No one knows what can replace the malicious mikruhu YD1521B.

[lpavel2004]

Good all! And yet still ask. Hike here, only we ask. Who will hear ?: I deducted that in DA971 there are two separate systems, dpc and dvd. My zhps works, the touch is normal, also on TV, but in the main menu the touch in general has died. There is a remote control, sometimes it works, sometimes it doesn't, it works mainly after a long power outage and then the first few commands. Since the zhps works without problems, I assume that you need to reboot the dvd part, right? Cton will tell you - which part is responsible for handling the wheelbarrow in the main menu? Gentlemen, thank you in advance! : thank_you:

[lpavel2004]

Gentlemen, and in St. Petersburg who will tell - where do they know DA971? I reflashed both zhps and dvd parts. DVD - 0827РЎ and 0930Р’ - the logo changes, the rest is not accessible, ZHPS - (

//savagemessiahzine.com/forum/d..80X234GPS_software.rar

) throws some kind of error in the file slave_q.exe 0xC0000005 00029D4C

- and everything remains as before - the touch in the main menu does not work, you can use the MODE button to call CDC, AV1, TV (touch works everywhere) and return to the main menu. Is that a brick already? Maybe he did something wrong in the message? I'm sorry.

[nslim2]

Da-974, when the machine is turned on, the mafon is cut down (it starts up) when it is turned on, it does not see the usb flash drive, you need to reset, the same with sd, if you then hang it at all, sore?

[Chkoniya111]

Kind! Does anyone have the firmware on Pioneer DA_973 sacgm2005-v4.12.7?

[Vampi]

Chkoniya111,
On alfessa.ru see the 2din firmware section.

[drakm2]

What kind of model help

Dear Vampi or a vampire ... stop sending everyone to your site. You are here looking for firmware, but do not give links to this site. And you send it to your own, where you ask users for a fee for the firmware downloaded from here. Of course you are a businessman, but you eat on a foreign member to heaven. IMHO. We got sly.

[Senpai_YSe]

Hello to all!
Help me please!!! I bought a SPH-DA 120 radio tape recorder and a MK809III whistle to it, tried to pair them through bluetooth, but got out a mistake. Do not how I can not decide if someone came across this, please help.

[SeCuRiTy_65]

Hello I got a radio tape recorder with a problem, it turns on for half a minute and you turn off, what could be the problem?
