GDB files

Both file types can be used to store and transfer routes and way-points.

GDB files are Garmin's own proprietary format. GPX files are, in essence, XML files that can be used across quite a few GPS devices. Garmin do have their own type of GPX file as well as there being a generic GPX format as well. As far as I know the Garmin GPX can still be read by other devices but also has a bit of extra data only Garmin devices and programs (Mapsource and Basecamp) can read.

More recent Garmin models (Nuvis and Zumos) usually use GPX files natively anyway.

HTH.

Cheers for that Bumpkin, a tour I fancy next year gives GBD files for the route instead of GPX files, as long as my Nuvi will understand them I'll be fine. :clap
