Hi, I left my lights on while at work about half a year ago; clever me I know. Needless to say the battery went dead and I had to jump start it. The radio was asking for my code, so I put in the code I had; which had previously worked. This time though, nothing. Doesn't seem to like that code anymore; I've tried it several times now. I'm probably going to buy another radio, but I thought I would try this as a last resort. Any suggestions would be greatly appreciated. Thanks.
