Play your XMp3 portable XM satellite radio in your vehicle with the CD-XMPCAR1 XMp3 Car Kit. The package includes a car cradle, power adapter, vehicle antenna, mounting accessories, audio cable, and a handy remote control. Connect the car cradle to your car stereo's auxiliary input using the included cable, and you'll enjoy great sound quality while keeping your XMp3's battery charged. If your stereo does not have an auxiliary input, the XMp3's built-in FM modulator lets you listen using your stereo's FM radio* when it's connected to this car dock.
