Cant quite work out what your saying here but my guess is that your headunit is wired with the dimmer wire which isnt a fault.

check the manual and snip the dimmer wire and that should sort it

hi dimmer wire shouldnt affect volume on a headunit. if u have wired the headunit in yourself make sure u havnt wired the sterio earth to the dimmer wire
have seen that before

[boxer1968]

ok il wire in a new earth .and see how that goes, cant understand how radio earth can be connected to dimmer but slowly will work though issues with the wires as guy i bought it from seems to have butchered it  thanks for the replys will crack on tomorrow.max

check any grey/whitre wires behind the radio, and chop anythat have ended up wired to dash. you want red (live) and brown (earth)
