Well, my radio (8.4) after (3) years decided to act up like nothing before.
The radio changes channels and apps on it's own, continually.
I've found if I touch a channel then quickly hit the app page, it stays.
If I hit traffic or off roads it will eventually stay.
I disconnected the fuse...
Try sending out a memo to all the Tech's who replace the steering dampener to Read The Instructions....there is a sticker on the shock tube and the buldge if the sticker is wrong. Mine was installed incorrectly and it took me 3 minutes to correct it.
I just received my notice on my phone. I guess I'm fortunate because I've had no issues with the front end (had a rocker arm fail at 11,500mi) so I hate to take it in. My JLSU birthdate was 12/18. We'll see.
