I have a route with 82 way points. I save it as a Harley .GPX1.1 as the menu allows and load it into my Harley-Davidson 6.5" Boom Box Infotainment System. When I up load the file, I upload it as a ROUTE. I tried uploading a TRACK, but the system wouldn't allow it. It gave me a transfer incomplete message. The ROUTE uploaded.
When I go to launch the route, the system freezes. I can't even delete it because the delete icon blinks, but nothing in the system works. It's frozen. The ONLY way I've found to get the system back up is to do a reset. Huge PITA.
I use the H-D Route planning software and that seems to work OK.
Thank you for your question.
I made a ticket of this forum topic to better help you with this problem.
