The cable is all you need to connect your SiriusXM radio, iPod/iPhone, or Smartphone to any vehicle or stereo system with a 3.5mm auxiliary audio input.
If your car stereo does not come equipped with an auxiliary jack (sometimes called a "line in" or "audio in" jack) you may be able to install one. We have kits available for many vehicle types. Check here to see if we have something that would work for your car.
