Summary: I have owned the Garmin M3 for about a year. The first thing I did was to update the software to version 2.5. As far as software goes I have no complaints however be aware that Garmin has limited a lot of nice features that I wish I had. For example don't pre-plan a trip and expect to download it to the M3 and if you want to stay clear of dirt roads good luck there is no filter for dirt roads on the M3.
Summary: the m3 has been such an asset to me...I work in sales and have to travel quite often. This unit has helped me find even the most remote locations. Sometimes it does take a sec to acquire the satellites but 95% of the time less than a minute. I would highly recommend this unit for anyone that travels for a living!
Summary: Our Son gave us a Garmin iQue 3 this past summer before we drove to Alaska and it was a great help in finding our way when looking for attractions on our trip. So we bought one for our other Son for Christmas. And after telling my Sister about it she ordered one for her husband for Christmas from Amazon also.
