Audio tone settings reset back to default

The tone settings (Treble, Mid, Bass) keep resetting to default. Has anyone else had this issue or know what the problem is? I hate having to keep adjusting them to my liking.

Thanks everyone! You have been a ton of help!!!

 

Sure you aren't changing sources and seeing the default? Should save them to each source (am/fm/Xmas/aux/Bt/usb)

 

Anyone ever figure this one out? Happens to me all the time too and can't put my finger on what is triggering it. Would the dealer be doing anything to it during service that would make it default to the flat EQ setting? Battery or voltage check or anything? Saved stations are intact, just the sound settings for each source. Strangest thing.

 

JBL?

 

Yes sir.

 

If you do a search of RAVs and Highlanders having the same problem; it's the JBL amp.

Do fade and balance reset?

 

Yes, they do.
