Default 2012 hatch - loss of bluetooth, onstar, compass

I've had my sonic almost 5 years now, and not too many issues at all. Now with over 100k miles, I am sure I will start to see things pop up here and there, like this electical issue...

A couple days ago something very strange happened. I turned the radio on and the pitch was HORRIBLE. Loud and muffled, even though the volume was at a minimal level. I turned the radio off and turned it back on. All was normal again.

As of yesterday I now have lost all functions of onstar (not that I ever use it), bluetooth (only the hands free calling portion, media works) and the compass on the instrument cluster. I have the more basic (not mylink) radio.

Any ideas?? Thanks guys!

I'd check the fuse inside on the driver's side by left leg. Look at the cover (I believe it is the second one from left and one row down) should be labeled OnStar.

I had a similar issue when my phone would be connected to Bluetooth then just disconnected and would reconnect in like 2 minutes. After I did the dealer update (recall) and it went away. That would be my suggestion, if you haven't done that.

Try disconnecting your negative battery cable, for roughly three hours, then reconnect, many times a reboot is all it needs. Good Luck!
