Weird problem coming up in my 2010 Hatchback: the audio system has suddenly decided to not respond to the ON/OFF and Switching controls. In other words, I cannot turn it off; nor can I change it from FM to AM to CD to AUX. However, the volume control is still working, and I can still use the in-car phone mic/speaker. It doesn't seem to matter if I have phone's BT turned on or off. Has anyone else experienced these issues?

The car has 105K miles with the standard GT audio system (single-CD; not the Bose). If I need to replace it, how big a job is this?

 

I would try a quick reset. Try disconnecting the battery for 10 minutes and reconnecting it.
Just a possibility it might work. It can't hurt anything.

 

Well, I'm a little embarrassed... turns out that the audio was fine all along. My phone holder was accidentally pressed against one of the control *****, which made it seem like the whole thing wasn't working!

However, it got me to thinking about whether I should upgrade the speakers, and how big a job that would be...
