Summary: Perfect for someone who wants one unit for both car and boat. While a bit bulkier than some of the nuvi models it has the same features if you can live without bluetooth and mp3. Its chartplotting ability and endless on the water maps make it an excellent lower priced unit for on the water. Large battery puts other units to shame when away from a power source. I replaced my outdated gpsmap 188 with one of these and no regrets.
Summary: I have no problem seeing the display in the Hawaiian sun. The marine charts appear to be very accurate. The only drawback I found is the battery has a life of half of that stated so I bought a second battery for a full day fishing.
Summary: Awesome unit for G2 Vision Marine, I bought one last year and now am back to buy one for a friend. I wouldn't go fishing without this unit! AAA++ and great guys to deal with. thanks again from Canada!
Summary: I expect a marine product to be sturdy. Dropped this thing 2" from the deck and it cracked. I owned a 276c for years and never had to worry about it. Display needs to be brighter. Auto guidance should be built in for this price. Lookout Garmin, smart phone apps are coming for you.
Pros: Acquires Satellites Quickly, Compact, Easy Menus, Easy To Read, Easy To Set Up, Large Screen, Simple Controls
Cons: Auto guidance Extra, Dim Display, Expensive, Fragile, Short Battery Life
