I recently unhooked the terminals from the battery to clean them. Ever since I hooked them back up, the radio will not hold the station its on. It will wander as if I hit the scan button or something. Was there something I was supposed to do after hooking the battery back up? Any suggestions would be greatly appreciated.

Hmm, I do car stereos for bestbuy. Id say the radio is the problem. Theres no setup ect. for a factory radio... Check connections but id say u have a bad radio.
