is the RNS-E worth getting?
how does it compare to other sat nav systems? i like the idea of having it all oem & not stuck on the top of the dash but i've not seen or used the audi nav software. is it actually any good? can you input post codes etc?
also, in terms of retrofitting it, the only thing that concerns me is whether or not you have to run cables to the roof for the gps aerial? i've read somewhere that you can tuck it in behind the dash?
also i have dis, but don't have vag-com to integrate the sat nav - would a dealership do this perhaps?
