Can you upload gdb or gpx files to this thing.
Not familiar with the subject matter so I'm a little confused.
I assume you can upload the files to a Garmin 2610.
Typically, you can upload 4 things to a Garmin GPS:
1. map segments
4. Tracks (sometimes)
GPX and GDB files may contain some of these four things, but they are not what you upload to a GPS. If you use Garmin's MapSource to create or save tracks, waypoints and routes, you can save them in either GDB format (Garmin's native file format) or in the more universal GPX file format. This file format can be used by a wide variety of different software packages from different GPS manufacturers to Google Earth.
So, if you get a GDB file, you will need to open it with Garmin MapSource to see the contents and upload to your GPS any part of it you wish. If you get a GPX file and have a GPX-aware software package (Garmin's MapSource, for example) , then you can do the same assuming it will talk to your GPS.
Lots of new terminology to learn, huh?
