If you're looking to get XM Satellite Radio in your car, and if you have an XM-ready Alpine stereo, this package is for you. It features the XM Direct radio, an XM antenna, and the adapter cable you'll need to connect the radio to your Alpine stereo.

The XM Direct radio is super-compact, so it will fit neatly in a convenient spot — under the passenger seat is the most typical location. The antenna mounts snugly on the roof of your vehicle, thanks to its strong magnetic base. The adapter cable plugs right into your Alpine stereo's CD changer port.

Once the XM Direct radio is connected, you can use your Alpine stereo to select channels (by category or station number) and view station information (artist, album title, track title, channel number, or channel name) on its readout.

The XM Direct radio is a universal application. It also works with compatible Sony, Kenwood, Pioneer, and Panasonic stereos. Should you ever switch the brand of your stereo, you'll only have to buy a new adapter cable (for the appropriate brand), rather than replacing the XM Direct radio entirely.

You must have a subscription to XM in order to tune in the digital satellite radio signal. (Satellite radio service is available only within the lower 48 states — not available in Alaska, Hawaii, or U.S. territories.)
