Alternatively, disconnect the battery ground cable for 1/2 minute.

When you power back up, it should restore it's brains. If not, it is done for - sorry. But many on this forum have upgraded to way better head units (myself for one!) and have the OEM radio sitting on a shelf in the basement. If you look, you CAN find one.

But do not overlook the idea of just upgrading to something newer. The Kenwood/JVC (and I think Clarion) marine radios are the same color as our dash and they sound WONDERFUL compared to the factory unit.

I put a JVC 660 in my car (it is discontinued), $80 at Best Buy and WOW did is enhance the sound in my car.
I had it wired up and installed in 1/2 hour.
