Hello
There are plenty of new devices on the market with newer hardware. Some of them have a new gps chip (minority) but most have new tmc receivers.
If they are not intended for iGO software (Mio, Navitel ...) then there are no drivers for that chip (they do not exist).
I’m not sure that’s the case with this model, but it’s a great possibility.
Tmc (and gps ports) is easily tested/scanned by the built-in mechanisms in iGO8.

P.S.
For GPS ports it is possible to do port forwarding, for TMC it is not, if it occurred to you
