I have a 2006 A6, I believe 2G MMI with no nav. There is DTS option in MMI but is greyed out. What is it for? Mine has 6 cd changer in glove box. Would like to know from members who installed NAV, how hard it is. I assume would need a nav box for the trunk rack.

Thanks!

 

i kinda asked the same question some months back.... but find this Audi forum does not have answers to share... for me still using web to find my answer,and for what ever reason even the dealer did not give me a straight answer. only that it would be complicated. not sure why because it does look like the wires are in the truck already.
