I purchased the Cycle Maps and tried to put them on my 67i and I guess there is no compatability.
My Montana 680 has the cycle maps and it sure is useful when I am mountain biking and encounter a closed trail. I can use the cycle maps to easily find an alternate route.
I'd love to be able to have the Cycle Maps on my 67i because I like to use this newer device and it's awesome battery length and updated features like InReach SOS while Mountain Biking.
