US Spec GT and Trailer harness

Has anyone with a US spec GT with a trailer hitch installed gotten the OEM factory trailer functions to work? IF so, how did you accomplish that.

I'm going to try to find out if the programming in the US spec vehicles will recognize an appropriately designed CANBUS interface module and act like the European vehicles and simply recognize it when a trailer is installed. I'm not talking about a trailer harness that does not talk on the CANBUS, but one that does. The X-series, I'm told, but do not know, work that way...install the harness with the appropriate module, and it just works, no extra programming required. It would be nice if the GT did as well!

I'd like some confidence that purchasing a kit from Europe will work, as the dealer tells me they have no way to reprogram the car to recognize it, and has little incentive to do it either.
