Hello All, Plunged for my first Audi! Love itâ¦â¦ well almost! Ive just bought a 2011 Audi A4 (B8) S-line 2.0 tdi and it has the 3g MMI without the little joystick. The trouble I'm having is it has NAV and the guy i bought the car from was a 'private dealer' who said the car had no NAV disc with it but got a mate to do one and will send in post. The disc arrived, clearly a copy, file size is 8.52gb but when i place it in the disc drive - it still says 'please insert navigation data medium' after reading an sd card can work, i bought a 16gb sd card, transferred the files, but still the same msg! I msg'd the guy i got the car from who isn't interested in replying to me so looks like I'm on my own. Anyone know the cheapest way i can get my sat nav to work instead of using my phone lol? Thank you all!!
