Whats wrong w/ my radio? Can't use dial or button to cycle to FM/AM. Help!

STC · 02-07-2012, 12:47 PM

This AM when I started my car I noticed that my radio was on the AUX setting. Thought it was weird since I didnt use my iPod last night.

I noticed that I can not use my steering wheel button or the iDrive dial to cycle to FM and AM. It only allows me to be go to CD and AUX.

Was there a setting I messed w/ that caused this? I have no idea how to fix it.

Now I can only get to the FM and AM by pushing the FM/AM button on the radio itself.

Pls help!

The block diagram of the audio system shows the Steering wheel control and iDrive control connect to the CCC (Car Communication Computer) through the K-CAN bus. I believe the AM/FM button is directly connected so the issue could be something with the K-CAN bus.
