When my daughter turns her car audio off, we loose preset stations.
Two questions to narrow this down - one, is it an aftermarket stereo, or a factory one? Two, with the key out of the car, can the stereo be turned on?
If it's aftermarket and it powers on when the key is off, then it's likely two wires are reversed in the harness behind the deck - the constant 12v wire and the switched 12v wire. The constant one is the yellow one, which always supplies power to the deck, keeping power there for the preset memory and the tone settings. The ignition-switched one is so that when the key is turned off, the stereo shuts off (this is the red wire on the harness). If these were reversed, the stereo would always be able to be turned on, and power to the memory settings would be lost when the key is turned off.
