Audio Systems: Sirius-Ford factory radio, ford sport trac, ford factory

Question
Ernesto,
Thank you for taking the time to help with this install. I removed my Sirius Stratus 5 from my previous vehicle, and would like to put it in an 07 Ford Sport Trac, with a factory radio. On this radio there is an AUX button, but there does not appear to be an AUX input. Do I need to purchase this AUX input separately? I used the Sirius FM Direct adaptor in the previous install. Will these two options provide the same quality sound?

Also, the power for the Sirius was taken from the radio using an adaptor that tied into the radio wiring, and looked similar to the cigarette lighter plug. I still have the male plug, but need the female plug. Are these available at a Radio Shack/Best Buy type of store? How difficult are these to instal? Thanks again.  

Answer
the radio is ready but you need to buy the AUX interface  
use this if there is a aux button
frd04-aux

if there is a also a SAT button  you need to use the FRD03-AUX/S

GOOD LUCK
