Please help! I have just changed my RNS-D for an RNS-E which I got from ebay. Everything is tip top apart from it doesnt link to the car now. The cluster display doesnt tell me what radio channel I'm on or show the sat nav bits like the old one did. I have tralled the net for answers but none of the ones I have found are not in idiots terms so that I can understand them. Does anyone have a simple guide as to what to do.
p.s. I have disconnected the Tuner module and linked together the coax leads and connected 2 to 8 and 3 to 9 on the 12 pin connector but this made no difference.
Please help before I smash it!

p.p.s. I also have a button fiteed which enabled the video to work while driving but this seems to stop and start the sta nav on this system.
