Question about Kenwood M-303USB Shelf System
Check the yellow wire connection on your wiring harness... This is the wire that provides continuous power even when the ignition is off. This is how the radio remembers presets/time and such. Every time you turn off the car, the radio "resets" because you dont have the yellow wire connected to an ALWAYS HOT wire.
If you cannot find a hot wire, then you can run a wire from the yellow on the back of your radio directly to the positive terminal on your battery. Dont worry, it doesnt draw enough power to run your battery down.
Most cars have a cigarette lighter or power port somewhere that is always hot. You could always run the yellow wire off of one of these.
Just find a way to get the yellow wire on a hot wire and your stereo will remember the presets.
