I just got my Nav screen replaced under warranty (pixilation dot) and while everything looks great, I noticed that the control buttons on the right side of my steering wheel marked +/- (2005 4.8is X5) now do not change CD tracks, nor change pre-set radio stations. The buttons on the CD/radio faceplate itself works, but the steering wheel option does not.
No complaint about the dealer, I just noticed and put out a call. I wanted to cehck here as well since so many of you out there have deep knowledge on such matters.
I saw nothing in the manual, nor drilling into the software on the equipment that allows this feature to be turned on or off.
Thanks in advance for any input!
