You will get problems only if you'll flash back to 3790. If you will use device as 34xx you will experience no problems. All features can be turned on by using xml files already posted in this thread.

The intact Non Vol memory will show 3450/3490 or 3750/3790 on about page , not 37xx or 34xx.
34xx is not matter because we have XML file to enable all features.
37xx will show the problems. You will loss features , example - Bluetooth.

You lost your model n., look at GarminDevice.xml in Garmin folder and you'll see the difference with the previous file in your backup, if you're interested in recovering it send me a pm, probably I can help.

Can 3760 be converted to 3490 (3D)?
Will the use of the xml files enable the 3D features?

The idea of backing up NV was not introduced until after I had converted 3790 to 3490. I do NOT have the 37xx or 34xx problem. Still shows 3790. Is it worth doing NV backup now, while still 3490? I don't think I would convert back unless selling unit.

For sure it worth to make a backup. Always it worth. For 3490 it's not so important, but for 3790 it's essential in case of damaged NV content. By making backup you will lose nothing.
