When I was in Rancho El Metate (Rancho San Juan De Dios) I saved the location on my Nuvi GPS. I remember it showed the coordinates as I was saving it. Now I cannot seem to find them. HELP.


You mean you want to simply read the coordinates off the face of your Nuvi and write them down? Or you want to download the waypoint and use it elsewhere?

My answer to the first question is I dont know how and to the second, I'm not sure it's possible.

Unfortunately, in viewing the Nuvi 760 manual online, I was struck by how badly it sucked with respect to GPS info. This thing almost seems like a mp3 player first and a GPS second.

Garmin is getting hammered on a few message boards I've searched for the seeming regression of the Nuvi line as a whole.

Which GPS are you using that you can actually upload a track (as differentiated from a route) to? I've always thought tracks were by their nature, read-only.

Lorenzo, the trickiness I've found with my 60csx and tracks is that you need to be familiar with the options in the track menu to understand how to Start a Track and Stop a Track and then have the wherewithall to actually remember to do this on each leg you want to record as a track. by doing this you save discreet tracks as individual units, as opposed to letting it perpetually "breadcrumb" and ending up with a huge file.

You can also "divide tracks" in Mapsource if you have large ones that you want to separate into smaller ones. But here you become somewhat dependent on the accuracy of the maps if you are looking to start and end tracks at a specific geographic point. Understand it is not the track that is inaccurate in this method, just the placement of it on the map.

I believe that .gpx files, which is what many Garmins wants to save tracks stored on the memory card (as opposed to storing on it's internal ram memory), is only lat/long recordings; no time or elevation recording.

However a track saved in its internal memory is a proprietary file and it should be able to share time, elevation, maybe even barometric readings with other Garmin devices.

As Hook states, the "Saved" track is stripped when it is saved to the card. The active track has all the data incl. speed etc. In a 76csx, if you set to record all tracks to the card, it saves all the data in a file by date, on file for each day. I use OziExplorer most of the time to edit, save, append, etc. I believe some of these can be done with MapSource, I'm used to using Ozi and find it much easier. With Ozi, saved waypoints, tracks, etc. can be loaded to many other brands of gps - but they have to have the ability to receive data from external source. Example, Magellan Meridian Gold will accept waypoints (or output waypoints) but will not output or accept tracks. I'm sure other Magellan units may handle tracks.? Lawrence units with a card can load tracks, waypoints etc to the card. Remember "Routes" are just a group of waypoints in a file that has them connected in a particular order. If you can load waypoints, you should be able to load routes.

Thanks Hook. Yeah I just wanted to get the Latutude and Longitude so I could put them on Google Earth. Oh Well! Thanks again.

Ok I figued it out with help. You have to plug your Nuvi into the computer with the USB and find the .gpx files and use Notepad to read it to get to the Latutude and Longitudes of the places you saved on the Nuvi 250W. Thank you to those of you who responded to my dumbness.
