I have an 06 FX4 with aux button for Sirius but no install from factory. Manual states press aux button for Sirius As I understand it there is a plug in the back of radio unit to hook up Sirius. When ordered from factory is there a seperate reciever for Sirius which is mounted under dash or is it somehow incorporated into the radio unit. In short, I want Sirius so do I purchase a Sirius receiver (specific for Ford???) and mount under dash and than plug into radio or is it a wiring nightmare. Tried a search, got nowhere. I do see on Ebay tons of Sirius units for sale but dont have a clue what to order??

:help

 

I just answered this question yesterday two posts below this one, to you! See the D3 Install link in my signature and you will see pictures of the factory Sirius tuner in my dash. If you are legitimately lost with no install experience at all you may want to consider having it installed by the dealer.
