Grand Canyon waypoints for Inreach Explorer
Hi all- I have a Garmin Inreach Explorer + and I want to put waypoints into it, for the Grand- Lees ferry to Diamond Creek. Either campground locations, or mileage points (or ideally both). Rivermaps have a .gpx file that they allow people to download- but when I try to upload it into my account, I get the message that there is a maximum of 500 waypoints allowed, and the file includes 699... (each mile marker to about 290, plus rapids, camps, etc). Anyone know how I can get at least basic waypoints into the machine (without adding each one, one by one)?
