I wasn't sure I wanted the NAV system, but I wanted all of the other options that came with the NAV system, and I am a gadget guy, so I didn't mind getting the NAV.

All in all, I am very happy to have gotten it, but not just for the guidance.

I like bullet points, I find them easier to read than long paragraphs, so I'll list some bullets.

* The NAV system is definitely not perfect. For instance, my house is missing from the system, and it is 13 years old. It also guided me a very long way through the D.C. area. On several occassions it told me "You have arrived at your destination" but my destination was actually somewhere down/up the road.

*Although not perfect, it is usually very helpful and does eventually get you were you need to go.

*I just used the system on a 600+ mile (1200 round trip) road trip, and it did a good job.

*We found it VERY usefull when driving down I-95 at 1am looking for a hotel. The system efficiently told us what hotels were up ahead. MOREOVER, the system gives you the phone number and has an icon that links to the bluetooth phone. It was very easy to click on the hotel, then click on the phone to check for vacancies. THIS WAS REALLY COOL BUT WAS ONLY USEFUL TO ME B/C I OVERRODE THE SYSTEM TO ALLOW MY PASSENGER TO ACCESS THE SYSTEM WHILE MOVING. I would have been MUCH less likely to use the feature if I had to pull over to the side of the road to start calling hotels.
