PIE TOY03-AUX Auxiliary Input Converter for Toyota Radios NOT compatible if vehicle has SAT button. The PIE TOY03-AUX Auxiliary Input Converter converts the CD Changer port of your factory radio into an auxiliary input. With this converter installed, you can connect any device that has RCA outputs directly to your factory radio without using an FM modulator. The TOY03-AUX works with most 2003-2007 Toyota vehicles that are equipped with a radio that has CD changer controls. The TOY03-AUX comes equipped with the new, smaller (approximately 3/4in) 12-pin mating plug and "Y" harness, making it compatible in vehicles equipped with factory steering wheel controls.
