I am picking up my '06 SCREW on Thursday and I ended up with the audiophile system with no Sirius. Does anybody know if I can add Sirius to my factory head unit?

 

It's a "Plug-n-Play" external module. No problem if you can find one.

 

I have the same problem. Two companies in California..Zarb Electronics (Corona, CA) and West Coast Distributors stated that they sell in-dash Sirius kits for the F150 Audiophile 2006's. Both companies stated that the kits are on backorder and it can take up to 3 months. I haven't confirmed this information with a part# or a followup phone call, this is only information I received by email. Other companies state they don't exist and they're on "backorder" because Ford hasn't released them yet. That's all I know for now.
