I did some investigating into this... I believe that a person can take the Google Earth layers you can download from the FS and convert them into GPX for importing into the Ride Command. In my head it works, but I don't have my unit yet to play with it.I was digging for that as well. We have Ride Command in the dash, and my Garmin 6" nuvi mounted in the back. As I know it will be easier for finding food/fuel etc. It would have been cool to upload those trails onto the Nuvi. I think the ride command trails should give us a general guidline for routes. While we have the Avenza app on our phones for when we want to use the color coding to be sure our wide machines are compliant.
I'm just under 62" on our G4 using the measuring advice in the video above, so I am good either way. But not the others in the group.
Friend left yesterday, and we take off on Thursday! I'm jacked!
Theoretically, you would be able to also add a layer for attractions/restaurants/ etc. and import them along with it.
