How to load a route onto a 3597

See if anything at https://www.reddit.com/r/Garmin/comments/dhd9ma/tutorial_how... will be of help. Take note of some of the early additions to the thread where some individuals have commented that the initial suggested method is unnecessarily complicated.

I'm sorry for being thick headed here, but is this for a walking or running route, instead of a driving route?

I've been plotting my routes using Basecamp. I create a folder in Basecamp for my trip. I expand my map as much as practical and add beginning and end waypoints and let Basecamp plot a route. If I don't like the route I add waypoints, that will force the route the way that I want. I name the waypoints with something practical and put a number in front of the name so that I recall which waypoint is next.
I export the file as a GPX and then use Trip Planner on the GPS to create the route.

Maybe this seems complicated, but I also found the link that was offered was complicated. I have no understanding about erasing layers and my approach doesn't require that I know that.

I do miss Microsoft Streets and Trips for plotting a route, because it it allowed me to add preset rest stops, such as a 15 minute stop every 2 hours and start and end times for travelling. Made it so much easier to figure where I might want to stop for the night.

Hence the reason I said review the early additions to the thread, which essentially mentions your method as being simpler.

I created a couple GPX files and loaded them into the GPX folder, But how do I view them. Maybe my previous Nuvi had a route button and this one does not. Whatever I did back then was easy.

You should see them in trip Planner if they are valid .gpx files containing routes. Do a Where to, Trip Planner

I have been away for a while. I will try that when I get back to it.
