has the head unit been taken out or has it been rewired somehow? if it had been, then could be the cause of live +ive wire been connected to the ignition wire... hope this helps andrew, No, all is original, nothing has been removed. hmz.. have you checked the radio ignition fuse? other then that i think there is something wrong with the stock head unit that you have. Yes I have checked the radio fuse, in fact changed it just to be sure. Looks like I'll have to pull the radio out, I was trying to avoid that. Thanks for your help.
