I have a route I sent to my GPSMAP62s. Basecamp adds a "1" to many of the WP's within the route even though none of the individual WP's have that. Additionally, when I review the route on the GPS some of the WP's display the contents of the "Comment:" instead of the contents of the "Name" field! This only occurs within the route, the individual WP's used to create the route appear normal.
I can edit the gpx file in Notepad and remove the "1"s but, in viewing the file, I can't see what the problem is with the files named with the "comment". For those, I edit the route in the GPS deleting the wierd WP and inserting the correct WP (actually the same one!). Rather tedious to get the GPS to display the WP name properly.
In looking at the gpx file, I noticed a series of "wpt"s in addition to the WPs for the "rte" entries.
As a side note to this, I would find useful, the ability to edit the name of a WP within a route.
