I have used the search function and not been able to find the answer. I recently retro fitted RNS-E to my A3. I have read on lots of forums that copied nav discs can cause the rns-e lens to fail as they have to work harder to read the disc. As a precaution, Ive just bought genuine audi 2-disc 2011 navigation dvd's. Ive just taken the disc out of the rns-e that came with the unit, and it actually has the same graphics on the front as the genuine disc, but looks very faded. Also, the underside of the disc has a blue/purle colour to it. Am I right in believing this is just a copied disc? Also, as soon as the new discs arrive in a few days, the 2011 nav disc that came with my rns-e will be redundant if anybody is inerested. It works fine, I just have ocd and am paranoid it will ****** my unit up. Ben.
