Has anybody had this problem? I don't know if I hit some combination of buttons by accident, but it's happened a few times recently. Suddenly the stock radio will loose all the presets. I'm getting tired of re-programming them.

This used to happen to a Sony pull-out HU that I had in my old car occasionally when I removed it for too long in cold weather - I think the backup battery would loose charge.

My radio lost presets today on a 50 degree day and there was no problem starting the car, so it shouldn't be a problem with the car battery.

 

Yeah, all bands on mine too.

Not an aftermarket HU.

My friend, who used to own an RS, Mr. Seek figity fingers, wore out his seek button in a Trailblazer in barely a year, and Chevy replaced his HU for him! I thought stuff like that is considered wear and tear and not covered!
