Q. Can I add an aftermarket iPod, XM, Siri, CD Changer or other input to my existing factory stereo?
A. Yes, in most cases. There are several ways to attempt this,

XM, Siri, iPod & other Auxiliar Audio Input:

• Presently, we are adding direct audio input to most factory car stereos with a 1/8 inch input, (2.5 mm). Call for applications for your car stereo and pricing

• Purchase the RF (radio frequency) adaptor, which works when the radio is  tuned to a specific FM radio station,

• Cassette adaptor

CD Changers: 

• Purchase the factory changer and cable, $$$

• Add an aftermarket changer with a special adapter (direct hook-up), which works provided your present factory stereo is CD ready

• Purchase the RF (radio frequency) adaptor, which works when the radio is  tuned to a specific FM radio station
