I just test drove an R/T for the second time yesterday. When I pulled back into the dealers lot, I played around with the navi for a while. I have to say, I wasn't impressed. The screen was small, the interface was anything but intuitive, and the thing was slow as molasses. Perhaps I'm spoiled by the one in my Acura. I had always heard that Honda made the best factory installed navis, but I didn't realize just how much of a difference there is between one system and another.
