After paying AVIN for support and finally receiving all of the updates, I am still having an issue that hopefully, someone can assist on:
--When I start the car the display shows "no signal"
--After 2 minutes I can click on the screen and see the Android UI
--I can do everything within the Android UI
The Issue:
--I can not get any sound out of the unit
--The I-Drive does not work
--The BMW stereo does not work
--When I click on "Car Info" within the Android UI I get "no signal"
Troubleshooting steps:
--Under factory settings 1314
--I switch the car to Alpine (also to Harmon Kardon)
--I switch between i-drive A and i drive B
--Save configuration to factory.xml file
--Still does not work
--I tried the reset sequence with the bmw radio "mute/eject/eject - No change.
I know the unit worked because when I test drove the car all of the functions, I-drive, BMW stock radio, sound from my iphone via apple car app worked flawlessly.
I think the problem is that the previous owner updated the MCU with the wrong firmware. The firmware you provided said CCC in the script, while the previous one did not. Could this be the issue? Is there a way to fix it?
If you can think of any troubleshooting steps, please HELP!
