I recently bought a 2004 Excursion; it doesn't have satelite radio or an AUX port. I want to add the ability to play my Sirius Stiletto 2 thru the radio directly (without changing FM stations as I drive).

Two questions:
1. What are the options (wired directly thru an fm station, replace the entire radio, etc.). In a previous vehicle, I had a wire that went directly from the Stiletto cradle to the back of the car radio which worked well, but it cost a bit to purchase and have it installed.
2. If I end up trying to set it up like my previous vehicle, how difficult is the installation of a direct wire to the radio (*I've never done anything with car audio before, but I'm fairly handy and I know how to follow directions). Not sure if I should attempt this myself or pay for a pro to do it.
