Sold the Mustang and several parts will be up for sale in the next few days...
First is a Ford OEM Sirius Satellite tuner, harness and antenna. Harness has all connections for easy plug and play. Easy install to factory 2006+ Shaker 500 systems (not sure if it will fit the Nav, Shaker 1000, or the non-shaker setups). All Satellite controls are handled by the Factory radio buttons-- easy to use (18 presets, scan by music style, etc). I mounted the antenna through the rear speaker shelf and had no reception issues, even with dark window tint.
Codes off the Tuner:
7L5T-18C963-AA (reference this code to see if it is compatible with your factory radio)
Sirius ID: SAT 018395739185
05stangkc has a thread on TMS regarding how to get your radio code to check for compatibility: http://forums.bradbarnett.net/showthread.php?t=50086
Price reduced to $200
plus actual shipping charges-- I won't try to jack you with additional shipping/handling bs. My ship-from zip is 85743; you can determine whether UPS, Fed Ex, or USPS is best...
