We travel the western states and have a SXS Canam Commander with the Garmin 650t, is there a map set that will show trails to use the ATV on? The topo map comes bundled with it
Well it comes with 100k Topo's. You might consider one (or more) of the Topo 24k map products. If you have specific "roads" in mind check the online viewer and zoom in.
BTW the 24k maps allow you to create routes that follow trails/roads. I don't think Topo 100k contains routing info.
It's a transparent overlay that only has the trails so you need to add it to the Montana and select both your topo map and the trail map so the trails will display themselves on top of the topo map.
If there are areas you care about that it doesn't cover, you can search for other trail maps at GPSFileDepot or other similar sources.
EDIT: That link just describes the map but does not provide a download for it. Here's the link to the home page for the map:
