Summary: There are several improvements that could me done to make these units better, and the Garmin customer service is NOT very good. I bought several different map packs to load on to this unit that were suggested for my needs of use by Garmin customer service, just to purchase and not do what was "claimed". Not happy with that. Also, the coverage is VERY limited.
Summary: My husband did lots of research (so did I) before purchasing this product. The product was the best on the market and he swears by it. The difference in the Montana 600 and the Montana 650 is simply the camera (which he uses 5.0 megapixels). If you don't use the camera, there really isn't much difference in the 600 but to him, the 650 was worth the extra money. This product maps your location and you can replay it when you get home and download it. It is amazing.
Summary: I've read other reviews on the Montana 600 series and Garmin's base camp before I purchased this unit, and almost didn't buy it because the reviews stating problems with base camp and the software was not user friendly. I how ever would disagree, I am not very computer savoy, and have never owned a gps or attempted to use software like base camp. But I figured it out with relative ease. I'm very happy with the Montana 650 and would recommend it to any one.
Summary: It made more sense to get a GPS you can use on and off road. You can't do the reverse. The Navi series is not designed to withstand the outdoor conditions as the Montana was. So this is good for any situation.

Summary: Garmin Montana 650, purchased 12/2012 Preface: I first wrote my review without having read any other reviews here. This gadget has had a lot of firmware changes since it was initially released that have fixed tons of serious problems so you really need to consider when the review was posted. Since my posting I looked around and feel I need to make a few more comments since mine is less of a review than a suggestion of how to use it and a bit of a tutorial. So...
Summary: Garmin releases their products before they are finished. This product had so many bugs when I first got it that I almost returned it then. But I decided to wait and hope that future firmware updates would fix most of my complaints. Well, I'm still waiting. I do like most things about this unit however which is why I still have it, but I hate it half the time and love it half the time.
