Hi All, I had a problem with no radio so removed RNS-E and checked connections. It was a loose connection. Sorted! Now I have radio back. Then... Im not sure what happened next when putting all back together. It tuned off. I looked at the screen and the bottom part of the screen there were fine grey lines running horizontally then they faded and now completely blank. I have checked fuses on side of dash and under bonnet and can't seem to find one blown. I have checked 15amp in actual RNS-E and all fine and held down on/off button for 30secs. I have also unplugged unit completely for over 10mins. I have a 6CD changer and that also is not powering up. I have no buttons eliminating on RNS-E or 6 CD changer when headlights are put on. Anyone know what this could be and how to resolve?
