<PartNumber>006-B0827-00</PartNumber>
<SoftwareVersion>760</SoftwareVersion>
<Description>nüvi 250W</Description>
</Model>

So that would mean HWID = 0827. There is no file in the Garmin folder by the name trafficprovider.xml. Can I copy this from a nüvi 255WT which I also have, or is this file unit specific?

FW version = 7.60. This is unusual for a nüvi 250W, as the latest version for this model is supposed to be v4.10. That makes me think it is loaded with FW for nüvi 255W for reasons explained by Neil in post #2. Assuming that is correct, it would also mean this unit should be traffic capable...
