Hi i have a 2.0tdi 170HP 2011 R-line. I had an old firmware on my RNS -510 and upgraded it to 4020 firmware. In the earlier version my BT on the media section would stay turned on however after the upgrade the BT only comes on if i play music or similar (It stays greyed out otherwise).
I have the DYNAUDIO package in my car basically what happened was that when i upgraded there was no sound in the system so i had to recode it at the dealers, but im wondering if they might have coded it wrong or something.
Any help ?? Which coding should i use on 5N0 035 730 D
Thanks again
Kind regards
Matin
