Summary: Used my new GPS around home once to learn how to use. Then took it on my first trail ride vacation the first of May and it wouldn't turn on even after changing batteries. And now the return program on Amazon said that the return ended May 3, that was when I was on vacation with this so call new GPS...
Summary: I've had mine a little over a year now, and I have been disappointed in the unit. For me, the major limitation is the speed (lack of) of the processor. It is very slow in getting a fix, and in showing your movement. My main use is in a 17' boat used for waterfowling.
Summary: I received this GPS for Christmas last year. Right out the box the thing has issues. It would freeze up and I would either have to hard restart it or take the batteries out. Also the left side of the touch screen was pretty much a dead spot.
Summary: I was disappointed with this unit because: 1) the compass only works when you're moving; 2) the touch-screen response is poor; 3) screen visibility in sunlight was poor; 4) I couldn't get the Summit series topo maps to show shaded relief on close-in maps.
Summary: For me this was an upgrade from the Magellan Meridian Gold. There are some things that the 510 has that are better and also far worse. The better: 1) The built-in entire US map--I used to have to manage how much of the country was loaded. This is a big time-saver.
but the accuracy from the satellites where I live never get better than 25-30 feet accuracy

Summary: Maybe it is just the area I live, but the accuracy from the satellites where I live never get better than 25-30 feet accuracy, not the 10 feet they claim. Also, it is very sluggish responding and if you are under heavy canopy or as soon as you step inside, you lose satellite.

Summary: It did not respond well to what I tapped on on the screen. Had batteries corrode and wreck on of the terminals that could easily be replaced if there was a replacement part but they don't sell those. They also wont repair the unit. I will never buy a Magellan again. I own 2 Garmins and love them.
Summary: I purchased this unit to back up my Raymarine chartplotter when sailing, as Magellan is one of two manufacturers that uses Navionics charts (the other is Delorme) which is the same chart system as the Raymarine. Here are some of my observations after several months of use. 1. Others are correct..
Summary: I do a lot of geocaching and I could not keep batteries in this thing. 2 to 3 hours and they were dead. I Magellan gps prior to this one and it was great, but this not so much. Recently aquired a Gramin montana 600 Like it
