Summary: I've now ordered this 610 three times. Unit 1 arrived and I familiarized myself with the menus and was happy with the operation. I then loaded the software onto my PC (Windows 7 Ultimate 64 bit) and connected the device.
Summary: I bought this back in Jan of 2011. I like the features but it has some bugs even with firmware updates. Things like random crashes & resets are somewhat common but only to a mild annoyance level.
Summary: What I like: accuracy, screen brightness, touchscreen, camera, quick-disconnect battery door, mini-SD capability. What I don't like: difficult to enter text for a log, touchscreen get wonky sometimes, the weight..
Summary: This is a good unit. The problems it has, is it eats batteries and it is almost impossible to read in the sun. All the features on it are good, accuracy is outstand except for elevation (It can be anywhere from 25 t0 500ft off). Batteries last only about 4 hrs, if your lucky.
Summary: The firmware that came with it did not work as advertised, it did not keep tracking when it went to sleep. I upgraded the firmware to the latest from the Magellan site and it now works as advertised. My last GPS was a Delorme PN-60. Unfortunately it got crushed when it fell in front of a Jeep.
Summary: I purchased this unit as an upgrade to our trusty Explorist GC. Was very disappointed as soon as it booted. The directional arrow is so huge on this thing, it practically covers 1/3 of the viewing area!
Summary: I am writing this as a retired test engineer with a GPS background, so I have time to mess around with my GPS and the experience to understand what I am doing with it. I have owned a Explorist 610 and a 710.
Excerpt: I have only owned this particular 610 for about 3 weeks and debating to return. I have a lot of experience using another Magellan, Explorist XL and only purchased this unit to utilize the newer features and ones that would aid in Geocaching but so far as fallen short.
Summary: i bought gps for when i go walking in the bush,i have not been able to use it because the unit willnot turn on,it will not turn on with bye battery power,it only turn when i pulled into cord on usb on computer,thanks garry.
