Hi, I replaced the Symphony II+ for the RNS-E without any problems, all wal plug and play but a few functions are still missing, first, the DIS is not showing the route, I know I need to use VAG-COM to let the car know that the RNS-E is there, what version of VAG-COM I need? my other question was for the bluetooth but I will check this in other forums after I update the codes in the car, may be is related with the same issue. I got the cable VAG-CAN and came with a software called Comander 1.4 I tried to use this but I never got a connection with the car. Do you know if this works? Thanks.
