There a Ford part # for the Sirius sat module?

I got my '07 with the Shaker 500 system which supports sat radio including display of channel names and info on the unit.

I was wondering if there is a Ford part number I can order, plugin and subscribe and be up and running?

I can't believe Ford would be shipping completely different Mach 500 head units for the sat option. Besides, when I test drove an '07 with Sirius, you just push the Aux button and it switches to that port. Which was the sat.

Thanks!

So the stations show uop in the stock radios display? And you control the sat frmo the stock radio?
