the sony marine radio excepts cd s but face does not light up for radio

Solution
Well you didn't list the model# so someone could look up the wiring diagram but I suspect the wire that needs power for the lighting to function was not connected.

I dont find a sony mdx50 model but typically:

yellow is continious 12v.
orange (lighting) and red (switched 12v) get connected to switched 12v line which is on/off with the key.

So it looks like you just need to hook up the red wire too.
