Well, the product arrived today from Ebay in perfect condition and I fitted it myself in about 10 minutes, so easy so you were all quite right

I was nervous the code wouldn't work, but no issues at all. I had to put some insulation tape around the GPS receiver and it then fitted nice and tightly in the shelf above the unit, as directed on this forum.
Everything works perfectly and mine has the LED screen and V7 maps with full post coding. It's a significant improvement to the car from the RCD310, in function and looks

The only thing that needs sorting is Vagcom coding, so the MFD shows Navigation directional arrows (it shows everything else).
Still can't believe I got it for the price I paid, given what the factory want, and also the stealers for retro fitting. Why would anyone order from the factory? The stealers quoted me £3,600 for the RNS510 and Bluetooth kit, without fitting

Getting Bluetooth fitted next week in Leicester.
Happy days............
