As an option for route planning check Harley Davidson's website for their Harley Ride Planner, it is free and not hard to use. For years I used Microsoft Streets and Trips but they quit supporting and updating that in 2014. On Harley's website you will need to create a user profile and then select Ride Planner from the drop down menu. The first few times you use the ride planner might be a bit of a struggle but after you become familiar with it you will find it pretty easy to use. All trips you create will be stored under your profile then any trips can be converted to a gpx file which you can download to a GPS. I have found that I prefer this to Garmin Basecamp and that it is free is a bonus.

Enjoy the ride
