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

The SD method is by far the easiest way to convert a US/EU 37xx into a 34xx. GarminExpress will then continue to supply it with update map entitlements according to the device's (permanent) Unit ID and all other files according to its new HWID of 1376.

Latest fw for US/EU 3490 HWID series is indeed V8.50 issued on Jan 7, 2020. That likely will be the very final version issued for the series.

I believe you've mis-typed and mean that your 3790 is running V5.10.
