Ok, I called Visteon who refered me to one of thier sales and service companies. They told me the Nav radio will work with sirius and display track information etc with the ford kit. My question now is what is this 'Ford Sirius Kit' and why does it cost $400 when a tuner is about $99-$150 and an adaptor could not be more than $40. If anyone has knowledge of the ford sirius kit or a different solution to display sirius on the Nav radio please let me know!
