Thread: Garmin Devices, their related HWID numbers and Software update Pages links Table

I have received a friend's nuvi with no label on the chassis (=no model number) and on the first page with the GARMIN LOGO it says: nuvi37xx (the known problem which I will try to fix later). There is a BlueTooth logo printed on the chassis, so I suspect it is a nuvi 3790.

Trying to find the nuvi's HWID I searched (according to your instructions) for "<PartNumber>006-xxxxx-xx</PartNumber>" in the file: nuvi\Garmin\GarminDevice.xml and I found 2 different lines (each appearing twice in the file):
<PartNumber>006-B0482-01</PartNumber>
<PartNumber>006-B0901-00</PartNumber>

The first line says the HWID is 0482 and
The 2nd line says the HWID is 0901
In the list of HWIDs in post 1, I can find NEITHER HWID=0482 NOR HWID=0901

Any explanation/suggestion???
