Radio/CD/Cassette power button suddenly stopped working?!?!?

[Rogertw]

One morning I started up the engine and hit the radio on button and nothing happened.

I switched off the engine, restarted, and the power came back on.

Next time I turned off the engine, the power was gone forever (or at least till now).

Nav still works fine, as does TV and computer, but no radio, cassette or 6 stack CD.

Any suggestions.

Just thought, could this be a simple loose power cable or fuse problem.

I had decided that the OBC module/screen was all powered by the same source, so it must be switch problem.

What the heck do I know
