The PIE JAGW-AUX Auxiliary Input Converter converts the CD Changer port of your OEM factory radio into an auxiliary input. With this converter installed, you can now connect any device that has RCA outputs directly to your radio without using an FM modulator. Compatible with all 2000 - 2002 Jaguar S-Type vehicles that are pre-wired for a CD changer, with the 12-pin CD changer connector located in the trunk. (This adapter will not work in the 2003 and up models.)
