There are lots of free topo trail maps specific to a local area on line that download directly into Garmin's. Possibly other brands too, I never checked that since all I use is Garmin. They're good for finding MTB trails and hiking trails, not so much for road bikes unless you want to plan a highway route. I checked out that trailink and the nearest to my location aside from highways was almost 70 miles distant. I'd be worn out by the time I got there, much less ride it.
