E39 - Can't Switch Audio Mode to Bluetooth #171
Description
Hello,
I received my BlueBus a few weeks ago and I'm having issues getting it working with my '02 E39 M5. The car is wired for a CD changer but does not have one installed; it looks like the CD changer was forcefully removed by a previous owner because the connector on the 3 pin power was ripped off and I had to put a new end on it. My car does not have a phone so I only have the 3 pin power and 6 pin analog DSP cables connected to the BlueBus. The blue LED lights up and the radio works as normal, but when I hit the mode button I only get radio or tape, it wont switch the input to bluetooth. I tried updating firmware on the BlueBus and that was successful but the issue didn't change. Something seems to be stopping the BlueBus from communicating with the car, but I don't know if the issue is in the BlueBus, my radio, or the wiring from whatever happened to the original CD changer. Any troubleshooting advice would be much appreciated.
