Thread: How to update Nuvi 1340

1xxx series was the first with some files in hidden .System folder, most importantly the factory-loaded maps. Browse the Tutorials, all such basic information is there to save members posting and waiting for replies. [Only registered and activated users can see links. ].

Don't use MapSource for updating maps, it's old and unsupported and makes errors compiling img files, use only MapInstall.

A good start here too:

Should I update this in the same way as for example a 250?

Depends what you want to update.
If it is system software (firmware) and ancillary files, use WebUpdater or Garmin Express.
It it are maps, then go with the suggestions already made by Neil and catymag.
Don't use MapSource. It's obsolete. Maps from recent years are not fully compatible with it anymore.

The gmaptz.img is the Time Zone map (contains data for time zones across the globe, including Day Light Saving details). That file should automatically get updated to the latest version when using WebUpdater or Garmin Express.

The nüvi 1340 uses the NT version of the European map, not the NTU (Unicode) version!

For details on how to update the maps, see here: [Only registered and activated users can see links. ] (as mentioned by catymag in post #3).


Edit:
gmapbmap.img is the world base map. No need to update.
gmapprom.img is the routable detail map, presumably the European map you're trying to update.
