Hello there. just become a member as just brought a rx8. though now i have no power to the radio or fans and the sat nav. its gone completely dead. Its on a 53 plate so if anyone has any ideas i would really be greatfull.

 

I would remove the HU and check the connections.
Shouldn't be the 15A ROOM fuse unless you have other interior components (such as the lights) that doesn't work.

 

Check the fuses anyways.

 

Thanks for the help people. But the fuses seem ok and the connections are all in. Still no joy. Would it be a good idea to try a new HU?
