What is MCU - In short: The MCU (Microcontroller Unit or, according to other sources, the Media Controller Unit) is a stand-alone computer, usually performed on a separate motherboard with its own processor, memory, and programmable inputs and outputs. Peripherals — a radio receiver (radio tuner), a DVD player, a Bluetooth hands-free device, a low frequency amplifier, and others — are connected to the MCU. Another part of the head unit - the computer running the Android OS - interacts with the MCU, transmitting commands to it and receiving responses to them. More details about the MCU can be found:
