so my car died and i charged the battery. once i charged the battery the navigation asked for a code. i dont have the manual or the code so i had to take out the navigation in the trunk to get the serial number. i got the serial number and got the code. ok now im excited i finally have the code after hours of being on hold and a bunch of bs. so i put the navigation back in the hook up all of the wires correctly and now the navigation wont even come on. so any ideas of how to get the damn thing to turn back on?
