I created a route in Basecamp 3.2.2 with the TOPO24K West map set by creating a series of waypoints, then using the "Create Route..." dialog to put the waypoints in the expected order. Actually, several routes, which I used on a multi-day hiking trip over Labor Day.
I then transferred the routes, waypoints, and custom maps to my Oregon 550t (running firmware 4.50).
While in the field, the waypoints never appeared on the route in the Oregon: it was just "Trail", "Trail", "Trail" and "Trail" - no mention of the waypoints making up the route. At first I thought that it just wasn't printing the waypoints but...
Eventually, my planned route diverged from what I was actually doing, so I created a new route on the handheld the same way (waypoint 1, waypoint 2, etc.) and now the unit properly showed directions as I navigated the route: "NW to <waypoint1>", "N to waypoint 2," etc.
So did I do something wrong, or is there an issue with how Basecamp sends routes/waypoints to the GPS device?
