I have not used one myself but they are very popular in the ATV world with trails and off roading.
I guess it depends on what area of the country you live in and what you need your maps to do for you. For my use, which is mainly backcountry hiking and 4-wheeling, the maps have always been the weak point of any Garmin GPS...even after they re-did the maps 3 or 4 years ago. They lacked detail, terrain features were hard to decipher, and many trails just were not on their maps.The Montana 600 is very nice but a Nuvi 500 can be had for
under $200 and never had a problem with their maps.
Guess it all depends on how deep your wallet is ;-)

Thanks for the review that's just what I needed to make my decision on buying this. I have fought for years not buying one. When snowmobiling here in Michigan I don't need a GPS but wheeling I have gotten lost a few times and this unit would have helped me out.I have been using it for years. On my Harley's,
in my pickup and also on my snowmobile.
I love mine !
This guy is local to me and I have even donated
some mapped snowmobile maps to him.
Great write up on the Nuvi 500 on his site.
Check out his whole site.
