all handhelds and pdas

If you are looking for an excellent palm-pilot with a GPS add-on, this is probably not for you. It is not designed to be an outstanding palm. If you are looking for a GPS based nagivational aide with some palm capabilities, then this is excellent.

The time to acquire satelites varies quite dramatically, but it does. I have even managed to track my location whiles flying. The location and airspeed were dead on, but the elevation of 50 ft seemed to be a bit low, considering that we were at 29,000 ft.

Quick to re-calculate if you get off route. It has been accurate, with 1 exception. In Boulder Colorade (despite the basemap and detailed map being loaded, it couldn't find all the streets, and had me displayed in the middle of a lake once.

All in all I am very satisfied with this product.

As a GPS junkie, I appreciate just how slick this navigation PDA is. The detailed City Select mapsets that come with the PDA are very detailed, and give you voice guided turn-by-turn directions anywhere you want to go. Add a SD memory card and you have more than enough memory to hold all the maps you need plus MP3's and other Palm applications as well. The only drawback, and it's a biggie, is that after 3 weeks my IQUE 3600 has completely stopped working. Garmin has asked me to mail it back to them (at my expense) to be repaired (at their expense). Maybe it's just a bit of bad luck with my particular unit. If navigation was all this unit did it would be worth the money (it costs 1/3 of similar non-portable in dash vehicle nav systems with similar capabilities), but it is also a great PDA and MP3 player as well. If it continues working after Garmin fixes it, I wouldn't hesitate to reccommend it to anyone.
