Thread: Nuvi 35xx Software versions Summary

No, HWID (Hardware Identification Number) value is displayed in the Inventory page and in GarminDevices.xml.

Open the GarminDevice.xml file in your Nuvi Garmin folder using any Internet browser.
Find these text - usually at the start of the listing.

<Model>
<PartNumber>006-B0932-00</PartNumber>
<SoftwareVersion>260</SoftwareVersion>
<Description>nüvi 205W</Description>
</Model>

The B0932 number listed at the PartNumber is the HWID, in this case it is 0932 for the Taiwan Nuvi 205W.

now, I already know, that xml is on the nuvi drive. I've also found the HWIDstring...

...but please where is an "inventory page"? in the device menu or on the my.garmin web?

no, I was dummy, so I've searched for xml at local hdd folder C:\Garmin

Inventory page on nuvi: First press for about 10 seconds battery icon on main menu. You should get diagnostic menu. Click "Next" button till you get page with header "Version information". Click "Start test", then "More" and you should see "Inventory page".
