this gps is great but a little confusing. would like to know if their is a card with trail maps on it already or do i load them on, not really sure how this works or what to get to make this work for me on the sled, i have used it on the trails it pretty good as far as telling me where i am but would like to have something with the maps on it or how i go about in doing this or downloading them thanks for the help and advice

complete color coded maps available on gpssledmaps.com or the nyssa website
download them into mapsource
if you ride canada, I use toponav from gpsquebec.com

use lith batteries for cold weather
