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

For JUMP car the solution is clear NONVOL in secret menu. When restart and you has do every your setting, don't touch zoom level on map but turn off your navi. then restart and all is ok. If It's not, clear again NONVOL and now you see that don't jump

1) When the unit boots up it still shows 3760 while it is starting up. In the about screen, it is running the 7.20 software, but the model is still listed as 3760. In the "Inventory" diagnostic screen, Boot BLK, X-Loader, System" all show 3760. Is this normal?
2) Also while the unit is booting up, the Garmin logo jumps upwards and a bit to the right, before centering again. Is this normal?
3) When I connect the device to myDashboard, it says "Map updates are not applicable to this device." and there is no option to update the maps. MyDashboard recognizes it as 3760LMT which is normal, but how do I get the updates to work?
Thank you again for you help.

1. It's normal to show 3760 while booting. But in inventory page must be 3490 (HwID 1376): [Only registered and activated users can see links. ]
2. Normal. I had this some time ago. After some firmware updates logo "jumping" gone.
3. After 37xx update to 3490, device must be recognized as 3490.

Is this how everything should look?

In settings -> about:
Model: nuvi 3760

Here is a pic of the inventory:

B1376 in inventory page means that you have 34xx series device. Webupdater (and Mydashboard) must recognize it as Nuvi 3490.

No ! .

I'm glad that at least my misfortune has served to update the post, I'm sure I'm not the only one with these difficulties, rather look foolish asking but at least I will not stand idly by, I feel confident with the support of you.
Believe me I've read a lot but for some reason it does not work.
