Does anyone have a clue regarding communication between a car radio and a CD-changer? To be more specific Ill split this in two: 1. Hardware Car radio has an 8 pin mini ISO connector: audio stereo input (3 pins for L, R and GND), digital (3 pins probably TX, RX and digital GND), and the other two pins for +12VDC (permanent) and +12VDC ( PWR ON). 2. Software Communication protocol used is D2B or Domestic Data Bus. I didnt find any information about this protocol. During PWR ON radio detects the presence of a CD-changer and then include this device in audio source list. You can then switch the sources: radio FM, radio AM, tape and CD-changer.
The problem is to trick the radio with a device to validate the CD-changer input and use this as any AUX audio input. I know it sounds like it doesnt worth the effort but I always have a lot to learn from such hopeless tasks in the past. Do you know where I can find information about D2B protocol ?
