Thanks lads, just checked fuse its ok by the way its fuse number 7 which also is for the phone and that has never worked since ihave had the car. Everything else works i have TV and Satnav picture but like i said no sound. There is a small amber light next to sound button which should light up when pressed to on,this now doesnt work.It only happened yesterday and the only thing i have done is retune the TV,but the wife is worse than me she may have touched a wrong button ??? Can i disconnect the battery to reset? Thanks again Bob
