Use Harley Davidson RidePlanner for Garmin custom routes

Revisited this problem of creating a route in Google maps and sending it to my Garmin 2455LMT.
I found a post by a guy named Bucky about using HD RidePlanner.  It works just as well as Maps and has a direct export to GPX file.

1. Create your route
2. Click on GPX Sync
   [The garmin chrome plugin is no longer supported in chrome so you'll need to use manual mode]
3. Select Manual Mode
4. Export the gpx file - Give your route a meaningful name
5. Connect the gps to your computer
6. Copy the gpx file to the storage on your 2455lmt (mine has a memory card so I copied it there)
7. Disconnect and boot up the gps
8. Go to Apps -> Trip Planner
9. You should see your route show up as the name you gave it above.
10. Off you go!

Update - What happens with multiple segments...

Each route segment from waypoint to waypoint will become a separate trip in the Trip Planner.  Which is probably a good thing.  They will be named "TripName", "Tripname 2", "TripName 3", etc.
These names are embedded in the GPX file so you can edit them before importing into the Garmin which is a heck of a lot easier that afterward on the Garmin.
The GPX file is in XML format, however, not in human readable format as there are no CRLFs.
I used Visual Studio to open the file and Format (Edit -> Advanced -> Format Document) it to make it easy to edit.
You will find <wpt> and <rte> segments so it's pretty self explanatory.  By default, the address is used as the name of the waypoint.  The first route is given the name you enter, then the additional ones are suffixed with 2, 3, etc.
If you modify the route by adding a draggable waypoint, each new waypoint will be named "Via Point {N}".  Might want to rename those as well.

What's nice about the RidePlanner (vs creating the route in Google Maps) is that it only creates a GPX file with the waypoints and routes defined with the waypoints, leaving the exact routing up to the GPS device.  The GPX file that I ended up with after making the route on Maps had a track with an explicit list of coordinates - when the Garmin tried to lay these down on the road map, it was a mess.  This is much cleaner.
