1995 Cabrio Factory Stereo Lost Power

[grovey]

Help!

We have a 1995 Cabrio with 6CD changer. I stopped the car briefly just after ejecting a cassette, and when I restarted the car it had no power. I'm not sure if it lost power when I ejected the cassette, or just when I restarted the car.

It has cut out on me a couple of times in the last year and asked me for the access code to let me use it again, but I'm not sure what's going on now. It doesn't seem to be either the main fuse for the radio or the fuse in the back of the unit. All of the connections in the back appear to be ok.

Is there any way I can test if it's the unit or the wiring?
