Summary: Product worked fine and was relatively straightforward to setup. Features work as advertised although initial time required to lock onto satellites seems overly long. My primary issue is with the additional maps that are required - you need to buy both topographic and road maps [at about $100 a pop] if you plan to use offroad and on-road. Plus the topo maps are over 20 years out-of-date for my town making me wonder if they have any accuracy or relevancy at all.
Summary: The Vista CX is a very nice GPS with great features EXCEPT the map software is not Mac OS compatable. You cannot upload maps or use any features which benfit from creation on computer based detailed maps. You can purchase the Garmin memory cards with map info and then establish waypoints etc., on the unit itself, but forget about the full functionality of planning, and mapping points and then uploading to the unit.
Summary: The first Vista Cx I purchased died after only 3 days of use. I returned it to Amazon who immediately and painlessly replaced it. The second unit lasted for 4 days until I fell waist deep into a stream with the unit in my pocket. Though it was only submersed for a matter of seconds it immediately stopped working and water was seen internally around the screen. Garmin's claim of waterproofness for 1m for 10 minutes is utter baloney.
