Basically, you just plug it in. The Titans with Rockford and 6CD midline radios are prewired for satellite radio (either Sirius or XM). The plug for the satellite box is dangling just above the brake pedal. Undo the plug from the restraint and attach to the box. There are 'official' mounting instructions that involve mounting the box to the firewall, but it is alot simpler to mount it behind the dash above the drivers kneewell - there is plenty of space there. The remaining element to mount is the antenna. The mounting procedure will depend on which antenna you get. Some attach to the glass either at the rear of the cabin or on the windshield, others are magnetic and can be attached to the roof outside the cabin. the favorite method with the small magnetic mount antennas is outside on the rear roof and run the lead-in through the cabin brake light.
I mounted the one for my XM radio on the rearview mirror using double sided tape and ran the lead under the headliner then down the column by the windshield and under the dash.
