Hi everyone I'm in need of some advice.. I have a 2002 Range Rover l322 4.4 V8 vogue. The issue is with the radio/sat nav, my problem is I can get sound but only for 2-5 minutes at a time, when It goes off if I turn it off and on again it will repeat the above process !! Also I have nothing showing on the screen all I have is a blank screen ( except for the back light ) the radio does have a red light that flashes but that's it.. I have power going to the cd multi changer in the glove box and also power to the sat nav in the boot as the red light is on, but still no display and intermittent sound . I have checked for water/condensation but the boot is 100% dry. At first I thought maybe it was the amp in the boot but if I'm getting sound I've been told it won't be that... any help would be very much appreciated as not having a radio is annoying.. thanks in advance
