Hello, first time posting here. Don't want to waste anyone's time so ill get straight to the point.  I recently purchased the new Garmin Montana and would like to learn how to download and install maps to it.  I've used handheld gps's in the past but mostly just marking waypoints for hunting spots.  i plan on using the new Montana on some atv riding, mostly just Pennsylvania and West Virginia, but possibly other areas a well.  Can anyone point me in the right direction where I can learn how to do this and where I could possibly find trail maps?  Any help would be greatly appreciated as I'm looking forward to learning a lot more of the capabilities of these units.  Thanks again.
