Some other tips:
Most riders are used to NAV systems like Garmin. When you expect the same behavior of the Harley NAV you will be disappointed. So don’t.
Harley NAV always wants to navigate to the next waypoint in the list. These are called destinations. If you leave the route, for whatever reason, like a road block, the Harley NAV keeps recalculating until you’ve reached that destination. The only way to fix this is by using the skip function. This will skip the next waypoint which you will not be able to reach. The system will navigate to the next waypoint. Problem solved.
Harley NAV always navigates from the location of the bike to the first waypoint or destination. So do not reload the route halfway your trip. Unless you have given the waypoints proper names which gives you some clue what the best waypoint is to restart your trip depending on your current location.
When you plot a route in Basecamp, Mapsource or Tyre make sure you use a sufficient number of waypoints. The more waypoints, the less differences there are between the route you plot and the route calculated in the Harley system. And what is a sufficient number you may ask. That’s based on experience. If you want that beautiful small twisty road in your route, make sure you put an extra waypoint in.
Put waypoints after intersections and roundabouts. In the riding direction obviously.
Put waypoints exactly on the road. When a waypoint is placed just besides the road you want to go, and the NAV system finds a driveway or a small road towards it, it will navigate you in that direction. Could be very annoying. Remember: Harley NAV always want you to reach that waypoint. To avoid that: use the skip function.
Until 6 months ago I was still using my Zumo 550 from 2006. Wondering if I have to buy a new Zumo or switch entirely to the Harley NAV. And that is what I did. It is not that good as a Zumo. But when you know how to handle it, it works fine.
