Thanks for the reply, I had almost given up. Sat nav screen appears now and again mostly when starting the car altough the screen appears grey(ish)...as if somthings there. Funny I know, but thats's the only way I can descibe it. I've tried taking the CD out and powering it down, all to no avail. The car is fitted with a 6cd interchanger this has stopped working. I can only have the radio or single Cd player, I cannot flip between (radio or cd) plus they stop on after turning the ignition off................ This car is getting more the car from the Stephen King film....Christine everday. Any thoughts.
