Build custom routes and waypoints for use with Garmin Hiking GPS and Garmin DriveTrack 70LMT (waypoints only but accepts memory cards for garmin premium 1:24,000 topo maps); Awesome Google Earth Integration
Garmin Hiking Handhelds and DriveTrack 70LMT support Garmin's premium 24,000 maps and custom Routes/Waypoints via Garmin Basecamp software. Also consider InReach Explorer+ for Satellite Texting and SoS messaging (weaker GPS features and not supported by Basecamp). Ignore the dog tracker features of the DriveTrack 70LMT if not needed...this is Garmin's best driving GPS I've found that supports topo maps with off-road trails (great National Park driving trails vs Magellan)...unfortunately does not import custom routes from basecamp.
