Ok, I think I might have a workaround for you guys to avoid interstates and highways. Assuming you have your navigation set to "fastest time" you could go into your activity profile in basecamp and set the speed limits for highways as super low (like 5 mph), so they would never be the fastest way. The types of roads you can set speed limits for are: Interstates Major highway Other highway Collector road Residential street Activity Profile Route Options You can customize how the software calculates routes for each activity profile. For example, you can require the route to use roads for a driving profile, and you can calculate only off-road routes for a hiking profile. Select Edit > Options > Activity Profile > Routing, and select an activity profile from the drop-down list. Route Preference Sets the route calculation method for routes using roads. The Faster Time option calculates routes that are faster to travel. The Shorter Distance option calculates routes that are shorter in distance. The Curvy Roads option calculates routes that prefer curving roads for more scenic motorcycle routes. Elevation Mode Allows you to minimize the ascent for off-road routes. Road Type Avoidances Allows you to define the types of roads to avoid in routes. Feature Type Avoidances Allows you to define the types of features to avoid in routes. For example, you can avoid toll roads, climbing paths, or narrow trails. Area Avoidances Allows you to define the specific areas to avoid in routes. Speed Allows you to set your average speed for different types of roads.
