See attached image. This is my MapSource window and the inset is a screen capture from my Colorado showing the same route.
I have a Colorado 300 and the Garmin 24k Topo software for the Eastern US National Parks. When I plan out a route in Mapsource, it follows the trail, but when I view the same route on the GPS it does NOT follow that trail.
What am I doing wrong? I'm trying to plan a complex loop trip in Great Smoky Mountains National Park and would like to be able to follow a track or route on the GPSr.
