Summary: My company car has a built-in GPS unit and I have gotten to like it, sort-of. I have gotten lost in a rental car trolling around Silicon Valley enough to get a portable GPS unit. After some research, the Garmin iQue 3600 is what I ended up with and I paid about $700.
Summary: I was shopping for a GPS last year. I did a lot of research and considered this one, but ultimately decided upon the Meridian Color by Magellan. In my opinion the Meridian Color is a superior product with superior software, and it retails for about half the cost of the Garmin.
Summary: I've owned my Garmin IQUE for over a year, and it is now going back to Garmin again for repair for the 2nd time. The GPS works fine, however the internal memory is way underserved. It is imperative to have additional memory to download the maps.
