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 that won't work. This is the second Magellan GPS that I have brought that was a lemon. Should have learned.
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. I was finally frustrated enough that it is now my backup until I can find a more updated handheld gps.
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. I'm not sure yet of the detail that would be provided outside of the US. Hopefully it is better than its predecessor that only had city points and few roads--only major ones.
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. Ultimately, my Android phone with apps is more user-friendly.
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...it is very difficult to use and not at all intuitive. Confusing and poorly presented functions, and it does not come with a manual.
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. Any time it asked me a yes or no question it took about 20-30 minutes to get it to accept yes as an answer(the yes key was on the left) Contacted their "customer service" and after about 3 weeks of emailing back and forth they...
Summary: This product does seem to work pretty well, but touchscreen needs a lot of work. The touchscreen is not very accurate and usually takes a few tries for the screen to register the action. It does take a lot of getting used pressing in just the right place so that is doesn't 'go back' a screen instead of accepting the desired action. The unit can also be pretty slow in responding even after you have pressed the correct function.
Summary: I WAS VERY DISAPPOINTED THAT "BUNDLE" DIDN'T MEAN THE NAVIONICS MARINE SOFTWARE WAS INCLUDED IN THE PACKAGE. I WRITE THIS REVIEW SO OTHERS WON'T BE UPSET WITH THEIR PURCHASE. IF YOU WANT NAVIONICS YOU'LL HAVE TO BUY THE MAGELLAN EXPLORIST 510 "MARINE EDITION". ITS ABOUT $200.00 MORE THEN I PAID.
