Has anyone here had issues with the sound settings reseting after a while?
All other settings seem to stay as I set them the first time, but the sounds settings are resetting after a while, going back to the default settings.
Yes, it happens to me. I'm on 70.00.335 (EU version) but without the Apple Carplay/Android Auto hardware stuff. It also defaults to FM radio when I've been on a DAB station when the sound settings reset.
Now that you mentioned, I have noticed that the radio also resets to FM. Have you noticed what may be causing it?
I need to check what version mine is running.
Mine still does it on 70.00.335 although perhaps a fresh install will hopefully cure it. Please report back if you still have problems (or not). I might ask my dealer to do a fresh install of the same version. I suppose they can only say no or want to charge 's even though it's still under warranty.
