Battery died, now radio won't work???

brusrgrl

So my car was left on over night and had to be jumped the next morning. I didn't realize it til halfway down the road that my radio wouldn't play. On the screen it says COed 4. I've looked in the manual but found nothing on it. Do I seriously have to take her to a dealership over this or is there a trick to fixing it? Not sure if it matters but I have the Tape/CD player. Looking for some advice.....thanks KIM

Seems that it's a security thing. I guess if someone stole your radio, they wouldn't be able to use it because the radio would "lock" when it was powered back up.

Here's a video that shows a fix you can try
