Re: [GRASS-user] Making and Uploading Maps for Garmin Etrex Legend GPS - v.net.salesman
You need to do it as a route, not a track, to avoid the ends connecting. I did this last year, and I think it worked as one would hope. Here was my process: 1) Generate the vector line. 2) Reduce the number of nodes if your GPS is limited in available storage with v.generalize (this can require many iterations and tweaking of commands to get it right) 3) Export as a shapefile making sure that it is of type line, as this is a segment 4) Convert to epsg:4326 if necessary (ogr2ogr -t_srs epsg:4326 ...) 5) Use ogr2ogr or gpsbabel to make a gpx file (you can also do the simplify stuff with gpsbabel simplify rather than v.generalize, if you prefer) 6) Transfer to unit with gpsbabel as a route: gpsbabel -r -i gpx -o garmin -f gpxfile -F /dev/yourgpsdevice I think you can skip 5 and go straight from shapefile to garmin unit, but not sure.

Re: [GRASS-user] Making and Uploading Maps for Garmin Etrex Legend GPS
I see some room for confusion here. I think on Garmins the basemaps "built-in maps" are not vector format but raster format .img files. So the short answer is you can't dump them on the way you're trying to, you need to convert them. You'll need to look for a tool like this http://wiki.openstreetmap.org/index.php/Mkgmap but meant to work with the formats your using and the platform you're on. Hope that helps, Alex John C.
