I have a Nuvi 765t that I use on my motorcycle. Problem is the bluetooth audio will not pair with my Cardo G4 bluetooth headset. I think the original problem is with Cardo, but at this point I need a solution.

I found an article here on "Turn your Nuvi 510 into a Zumo 220" and I'm wondering if the same thing can be done for the 765t. My understanding is that the hardware is the same as the Zumo 660.

I'm looking to make the Cardo think it is pairing with a Zumo any other functionality is a bonus.

Any ideas?
