Now I've only been a member of the TL Community for about two months, but it seems to me that many people that post here for the first time are saying "Doh! I wish I had bought a TL with that sweet Navigation. How can I add it?". I think that anybody asking "Navi or non-Navi" should pay attention to this. It was the main reason that I even considered buying the car myself.

Just my 2 cents,
