Thread: Transform a Nuvi 37xx in a Nuvi 34xx for dummies

Yesterday I converted the Nuvi 3790LMT to Nuvi 3490LMT without any problems. I greatly appreciate your work!
my procedure:
0. The complete backup of all content
1. first reset NV
2. download fw Nuvi 34xx version 7.10 from Perry nuvi34xx_GCDFile__710.gcd
3. press RGNTool v0.84 to convert nuvi34xx_GCDFile__710.gcd to nuvi34xx_GCDFile__710.rgn
4. via updater v2.8 upload the nuvi34xx_GCDfile__710.rgn to the navigation.
5. On the card to the root folder expand the file convert37x34v.zip (in header of this thread), the tab to navigate ...
6. a few starts and restarts
7. Finally reset NV
8. download language files and help via GarminExpress


And I have a Nuvi 3490LMT including mediaplayer, video player and digital services via Garmin SmartPhone link app! It is fully functional in both GarminExpress and WebUpdate, including downloading maps.

BUT: the GPS reception was too bad, then I must convert the nuvi back to 3790 and good GPS reception restored. :-(
