I haven't had a whole lot of time to play with the new NAV unit but here are some things I've noticed compared to the one in my (traded-in) 2001 Acura TL:
- it would have been nice to have a touch-screen. The combination of twisting the little knob or cursoring around and pressing enter makes entry slower.
- unit doesn't allow you to enter a destination while the car is moving. I think this is becoming a more common feature but it sucks.
- routing is pretty quick, and re-routing (if you make a wrong turn) is quick, too.
- the system is very customizable, letting you choose whether to use tones, voice, or both. According to the manual, it also lets you choose whether to use turn-by-turn on the screen, just the next turn, map, or some other choices. Haven't looked at this yet.
- if you have the electronics convenience group (EVIC) the dashboard display can also tell you your next turn. Kind of neat, unless you leave the EVIC display in MPG mode
