Jumped in the other day and thought I'd stick a cd on; pressed button to turn it on (the rotary volume one on the left but no light, no cd screen, no radio screen and clearly no sound. The screen itself works fine, nav screen and menu arew all there. CD changer has power and will eject the cassette.

Checked fuses in glovebox seem ok, removed BM54 and checked the 10 amp fuse under the plug.

Is there anything I'm missing or is this a duff BM54?

Thanks in advance for any guidance.
