My aftermarket Kenwood car radio reset itself as well. It seemed to do this during colder mornings, when the car "hesitated" to start. This really started to piss me off since I lost all my setting ( including radio, Sirius, color displays…etc.)
Well I think I just fixed this by adding a 4.7uF electrolytic capacitor on the ignition wire (yellow) to the radio.
I’ll explain for all those non-technical people (very simple). Basically my theory is that power was being interrupted to the radio and the Yellow wire was not holding the 12V. Adding the cap across the 12V and gnd (black wire) adds a small amount to stored power if that voltage drops. As of this morning it was a chilly 29 degrees and it seemed to work like a charm. Normally the radio would reset itself during the initial crank of the key

You're reading My car radio resets itself, losing all saved stations and clock settings. This happens randomly and frequently during very cold winter nights. What could be causing this?
