Bluechart G2,

After a few initial problems getting started (due to hardware, not the software) and some much appreciated assistance from Garmin, I have been using the G2 charts on the coast of Maine with great satisfaction. I'm still getting used to all the features, but overall, am entirely satisfied with the product. There are a few things I would have liked differently, such as fewer keystrokes required to access a stored waypoint, but overall it is good. I'll continue to use it on all my boating trips.

   the software's pretty good. I say only pretty good, because I fish and boat only in coastal waters and that's what this touts. But, not all rivers, creeks and nav aids are included.
