How are wayponits saved? When I hook my Oregon 450T up to my computer I don't see any file that would be specific to the waypoints that I have saved on the unit. When I transfer to mapsource I see the waypoints on the mapsource map, however, I don't see any corresponding GPX file for the waypoint. I also have no problem sending the waypoints from mapsource to the 400T. Where and how are these files stored? Thanks.

I have a Garmin 400T with mapsource.

How come when I download tracks & waypoints to my GPSr they due not overwrite the previous version....they instead duplicate the track or waypoint out on the GPSr. For example if I have a track named 'abcd' on my GPSr and then edit and re-download I'll now have 2 "abcd" tracks on my GPSr.

OK...so I'm dslexic. Anyway, How do I view waypoints when my GPSr is hooked up to my computer? I don't see any file that look like my waypoints...I know I have waypoints on the device because I can view them on the GPSr. Thanks.

Yes, I meant .gdp. Thanks.

What is the difference between a GPX vs. A GPD fie type? I noticed that in Mapsource I can save as either file type and it doesn't seem tp affect the data, but when I'm working in expert GPS it only allows me to work with GPX files.

Also, I know tracks are saved as GPX, what are routes saved as? when I hook my GPSr up to the computer I can easily identify my tracks, but not my routes. Yet when I download from Mapsource the file I send to the GPSr (which I saved as a GPX file) contains Tracks, waypoints & routes how is this possible?

Thanks for the help.

Anyone use Expert GPS? Is it worth the money? Thanks.

How do I view and work on multiple tracks at once in mapsource? It seems I can only view 1 track at a time. I would like to view multiple tracks at once and be able to edit & combine them. Thanks.

This program will do just what you want, but it's only available in beta. I have not used it myself: http://www.gpx2img.com/

Mapwel can also make a transparent map and is pretty user-friendly: http://mapwel.eu/

I downloaded Mapwel....how do I use it to make a transparent map? can i upload a topo map in mapwel and then add the tracks or do i have to use a google earth map?

I would like to map some trails in my area on my GPS (oregon 400T). I would then like to take those tracks and put them on a map as trails. I would like to be able to then print out the map so I have a paper copy and then download the map with the trails back to my GPS device with the 'trails" on the map. How do I do this??? Seems like it should be easy, but I can't figure it out.

Yes, I can see it when I connect it to the computer, but when I go to the 'select map' menu in the Oregon, the map is not there.

Help - I downloaded a map to my Oregon 400t - I can see the gmapsupp.IMG file in the internal memory when I hook up to the computer, but I can't see the map to select on the device. Any ideas? Thanks.

I found the .img file and was able to re-name it. Just need to figure out why I can't see the track I drew on the map in mapsource. Any ideas? Thanks for the help.

How do I rename it once it's in the 400t? The file that I see in the unit is named ME Trails, the file I overwrote was named MAINE-topo.....where is it named gmapsupp.img?? Thanks.

I got it to work - I just sent it to the gps again and it started working. Another question - I sent another map to the unit, and now the 1st map I sent is gone...is this normal? you can only have 1 additional map in the unit? Also. I added a track to the map and i cannot see the track - how to you view saved tracks? I did include the track when i sent the map to the gps. Thanks for the help. (i'll get the hang of it soon).
