I got a Garmin Montana last year and love it. You can set up profiles for anything you want ATV, Snowmobiling, Hiking, Auto, or about anything so with one touch you have the set up you want with the maps you want. It even has a camera.
Yes you can get all the Michigan Snowmobile and ATV maps. V.V. mapping. Good to well below freezing ran it on the sled last year and never a problem. you can also get depth finders and lake mapping. Its not cheep but you only will need one for anything you will be doing. Also water proof.
