I know there is some sort of diagnostics mode, and I know I have used it before, but I kinda forgot... heh...

I *think* it goes something like this:

With the key in the ACC position and the stereo off, hold down the 1 and 6 buttons and press the CD button 6 times. I seem to recall this will drop you into a diagnostics/self check menu. There was some info about it online somewhere, but for the life of me I can't find it now.

If all else fails, disconnect the battery for a while and hope that resets something.

Good luck <img src="/forums/images/graemlins/cheers.gif" alt="" />
