XM INTRODUCES THE XM COMMANDERMT UNIVERSAL SATELLITE RADIO RECEIVER

Seamless aftermarket XM car receiver works with any AM/FM stereo

Washington, DC, July 9, 2007 — XM, the nation’s leading satellite radio service, today introduced the XM CommanderMT. The seamless in-dash XM radio will work with any vehicle’s AM/FM radio and will be available at retail later this month.

Manufactured by Audiovox, the CommanderMT is a total, all-in-one package, styled to seamlessly integrate into any vehicle’s dash and work with any automobile’s AM/FM stereo, regardless of make, brand, or year. The CommanderMT features a large, easy to read, four-line display and easy to use tuning knob for selecting and changing channels.

“The CommanderMT meets listeners’ needs for a clean, sleek and stylish product that can be easily be integrated to any vehicle without replacing the existing stereo," said Blair Kutrow, senior vice president, product and campaign marketing, XM. “This state-of-the-art radio is versatile, and works with any automobile make or model, including high-end luxury models, enabling listeners to gain access to more than 170 channels of the best programming and entertainment."

CommanderMT also includes a feature that will alert you whenever your favorite songs, artists, or sports teams are being played on another channel. The radio offers quick channel navigation with the option to program up to 30 favorite channels, or press number buttons to enter and move directly to the channel you want, and easily “jump" to the previous station you were listening to.

The CommanderMT works with the portable XM Mini-Tuner, a compact removable cartridge containing the XM subscription that can be used to access XM Radio programming through other compatible car and home products.

CommanderMT is available for a suggested retail price of $179.99.
