Hi I have a new 2004 model Jeep G C with original digital radio with navigation. My problem is that it looses the memory. I have the car running or in Park, no seat belt on, set all radio stations, push the set button on the door than the 1 button for my black remote and it seems to be programmed. Like when I did this yesterday it was ok as well as this morning, but at lunchtime all the radio setting was gone. Any one know what it cold be?
