Summary: I could write a book on this, but I'll spare you. I like the 276C so much, I bought one of the few 478's because they are so similar. Yes, it's a marine chart plotter/fish finder/sounder of some sort, but I've been so very happy with it as a motorcycle gps that I now keep the 276C as a spare to my...
Summary: Without having seen one of these 'in person', I was surprised at how small the screen is. Also surprised that even though the device defaults to 'marine mode' (which is what we purchased it for), we had to spend another $150 on a data chip to see anything remotely 'marine'.
Summary: I had been using a Color Street Pilot for a couple of years for both auto nav and to feed my TMD-700. Been using a OLD GPS-3 in the YL's (KE5EVL) car. The GPS-3 started losing its screen --so--time to upgrade. My Brother-in-law (K1LCH) has a 276C that I had wired for him.
Summary: I'm a Amazon River Pilot and I use GPS only for marine navigation. The GPSMAP 276C is a good equipment but in my opinion has too many features that most people do not use. Before I had a 176C that was much more easy and quick to use for marine navigation: it was made for that.
Summary: So far, we don't have this completely up-and-running. It hasn't been particularly intuitive as far as set-up goes. (At least for us, and we're usually pretty good with technology.) It looks as though it will be good. Maybe after we actually take it out for a "spin", we'll have better insight.
Summary: Yep 5. GPS2, 3, 3+, 5 and now a 276. It would seem I am a good customer. I ride ATVs all over the back country of the west. Each GPS I have owned has been an improvement over the last. I wouldn't leave home without one. The 276C is great.
Summary: First, I purchased my 276c in September of 04 which means I've been using about 3 months. It was purchased to replace my Garmin GPSIII that I had used for around 6 years. The GPSIII still works great but has no detail maps available and no turn by turn directions, but for basic Lat/Long it still...
Summary: The Garmin GPSMAP 276C is a powerful GPS, with many features. It can do topo, sonar, car navigation, bluechart marine. It works well, although it is not as user friendly as some units. Be prepared to read the manual several times to be fully comfortable using this gps.
Summary: I am happy with this chartplotter but right now I wouldn't recommend it. For one thing Garmin nickels and dimes you to death if you want to actually use this. The memory is very expensive and proprietary. You need to buy additional memory to download any charts into this device.
