Artem_dc, Sound settings are knocked down when the ignition is turned off (I already changed the wires with yellow and red places) ... in the engineering menu, temporarily, I cut the volume levels.
After turning off the ignition, the mafon eats 0.5A for another 20 seconds, then it seems to be cut off, there is nothing to measure the current below 0.3A.
