Stereo & Electronics - ? about radio

I was having trouble with my car today. It didn't want to start and was acting like the battery was dead. I found out that the problem was just that the positive terminal was loose. I tightened that and everything is fine except that the radio display says LOC on it. I tried switching modes and everything else but i can't get any music to play. Does anybody have any idea how to fix this? Thanks.

What you are experiencing is the built in theft-lock feature. IF enabled, the head unit goes into LOC mode if power is lost. This suposedly prevents thieves from installing it into another vehicle. There is a thread on here explaining how to un-lock it.

I'll try to find the thread on here. thanks alot
