I fitted a Goodmans head unit into my Move a few months back and after a long journey from Norfolk down to Wolverhampton where I'm now at uni, the head unit stopped working so I removed and unplugged it and then put it back in, after this the central locking stopped working and the head unit doesn't appear to be recieving any power.

I checked the central locking and radio fuses in their respective places and I'm not sure if they are blown as they are like a tiny box kind of thing, not the blade fuses that everything else appears to use. I took the suspected blown fuses into Halfords and Maplins but they said it was probably a dealer specific part.

A little help here? I could photograph the fuses if that would help
