It's been forever since I've posted anything so I just wanted to start by saying hi guys. I had to replace the battery in my 07 GT the other night and since then my radio will not light up with the rest of interior lights at night and every time I try to play music from my phone thru the auxiliary cable port, I get the no auxiliary message on the radio. Other than that the radio works just fine. Anybody else had this problem after replacing a battery? I've done everything short of just taking the radio out. Also has anybody else had a problem with the charging system in a mustang around my year model? I've already replaced the alternator and that battery had only been in there since 09
