Yes that service letter explains the control unit possibly needs replaced. I had mine done 3 weeks ago and my problem went away. While they had the car they replaced dash lights as well as mentioned in a previous post.my cars an october 08 build, they extended the warranty coverage on the radio?
I had just done a 2.5 hour drive, shut the car off, and when i turned it on next, no audio, all the audio buttons don't function, and audio is stuck "off".
has anyone else had this?
