The Audiovox CNP2000UC XM Direct 2 Car Kit is a universal XM satellite radio programmable interface adapter. Designed for use in the car, the XM satellite radio combines a programmable adapter and the XM Mini-Tuner, where you can program the adapter with your home computer to work with the in-dash receiver. You easily can change channels and see programming information on your stereo's display. The adapter can be reprogrammed to work with a different dash receiver, so you can use the compact XM Mini-Tuner with your XM-ready home receiver or in another vehicle with a compatible dock. A subscription to XM is required, as well as an additional, brand-specific cable that connects the adapter to your receiver (not included). Audiovox offers a one-year warranty.
