Pros: Large bright display, text to voice, bluetooth, portable (built in battery), slim outside case
Cons: Hands free is lousy, expensive, traffic updates are useless, not MAC friendly
The bottom line: Good product, text to voice is great, bluetooth.
It does what is says, it gets you from A to B in style. Initial signal acquisition sometimes can take 5-10min other times it pretty quick 1-3min (not sure what its dependent on). Once it acquires the signal direction routing is fast, and if you miss a turn it reroutes you instantaneously. Voice recognition is great, it really does help when you have to make a bunch of quick turns and can not afford to be glancing at the screen. The device allows you to input and save (500 max) custom way points (POI), which are searchable by categories or you can spell out the name. During navigation the device allows you to add or insert one POI as ether a new final destination or as a intermittent point in the present route. The device has about 6 million items in its data base, so far I was able to find most of my queries, however, some of the new places are not listed (ever now and then Garmin will release map update which supposedly will list some of the new addresses, connect to you PC and sync). Also while conducting a search you can touch the phone icon and call your destination provided you phone is connected.

The traffic feature has a great potential however, it does not live up to the hype. The traffic hazards that it did show were outdated and have been cleared a while back. It would sometimes show uncongested traffic where in fact traffic was heavy or completely stopped and vice versa.

Bluetooth is not always reliable, not all phones can pair easily with the device. Some have problems connecting, staying connected and/or utilizing all the hands free features of the device, Motorola V551 and Treo 750 worked ok, iPhone seems to work much better. The volume and voice quality on the hands free is too low and too degraded to serve any practical use unless you're stopped and your windows are rolled up.

MP3 player is useless unless you like to listen to your music in mono on a 1" tiny squeaky speaker.

All in all pretty good device. I bought mine in December '06 for $800 at Best Buy.
