Hi all. I have had to buy a replacement infotainment screen unit as mine has cracked. When it arrives, can it just be switched across or does it have to be coded by a Seat/VW specialist to the car? I know a garage that has all the vag software ect. It's the same part no as the original and I am only changing the screen unit not the glove box part. It came out of a car with the same spec from the same year. 2014 leon fr tech packThanks for any advice.
