Summary: Garmin has gone over the top with this unit. I have used it for city driving, hiking, and geocaching. The touch screen is easy to use and once you have the icons setup for your needs it is even easier. I have a GPSMap62s that I have used for the last several years and it is still a great unit. The Montana 650t is much larger, however the increase in screen size was worth the price. The 62s on average would get me to within 10ft of a geocache, the 650t does just as well.
Summary: LOVE, LOVE, LOVE our Montana. It took a bit to get used to but I really like how fast it locks in to the satellites and love the fact that it has the rechargeable battery pack. Garmin is the ONLY way to go when it comes to a handheld GPSr!!!
Summary: I bought this GPS to use on the motorcycle mainly because of its long battery life and water proofness. I can also use it on my boat if I get the marine maps for it which I will next spring. Highly recommend buying the upgraded maps for it, they provide a bunch more detail than the stock maps.
Inferior support and products than previously experienced

Summary: Purchased the Oregon 550T during 2009 and would rate it five stars. Most of its time is spent on my sport motorcycle and off-road motorcycle. Durable is the word for 550T. Purchased the Montana 650T with the same expectation of durability. The larger size is great, but it is larger. Mounting to self or motorcycle is inferior to 550T, and the back cover is sloppy.
Summary: A week after purchase I headed into the backcountry. It performed as expected, and I was pleased with the battery life. The unit is a bit bulky making it a little difficult to find a way to pack it, and have it accessible. The camera is convenient, but again the size of the unit made accessibility difficult. The documentation for the unit is useless, and that is being kind. You basically have to figure out how to use the unit by trial and error.
Summary: Perhaps an unfair comparison, but I naively thought that this GPS would have technology that rivaled the smart phone. Instead, I found, from a user perspective, a primtive device -- small display, poor illumination,lot of menus with no explanation and utterly unintuitive. The owners' manual is a joke -- very basic instructions with no explanation as respects the jargon being used.
Cons: Hard To Read Maps, Not Intuitive, Poor Illumination, Poor Instructions
Summary: we all use touch screen devices these days and I am a computer science major. This device is a pain in the butt. I do search and rescue on horse back. it is difficult to maneuver to the correct screen with slightest touch it jumps around. for some reason the trip odometer resets itself to 79 miles without my even accessing the function which of course looses all my data.
Summary: My husband is going to Colorado for an Elk hunting trip in the mountains. He had a Garmin before and it was over 12 years old and just quit working. He did alot of research before picking this one. He loves it and uses it all the time. He has now gotten into Geocaching and we take our granddaughters with us and he lets them look at the screen and determine which way to go.
