Appearance mainly. The 60 and the 76 are virtually the same unit with different cases, screen orientations, and button layouts.

Most guys would prefer the 60 for ORV uses. The 76 is more oriented towards the boating crowd.

Either will work fine, just pick the unit that you think you'll like better when it comes to where the screen and buttons are located.

can you load the michigan snowmobile trail maps on top of road maps of the U.P on the 60csx?

anyone out there have one of these with the roads of the U.P. on them. I want to know how many back roads are on them. I would like to be able to take some back roads around the trails when they get rough.

Thanks for any info

I have the 60 cx and i use it for allot of thing like two tracking with the jeeps and snowmobileing atvs and just plotting propertys with the mapsource it will give you the back roads some have names and other don't but its a road you wont be desaponted in the unit.
