The XR9 features a built-in FM transmitter which broadcasts XM directly to your vehicle's FM radio. You can search by channel number or category, and program up to 20 presets. The receiver can save the names of up to 24 songs, and alert you when any one of them is playing on XM. You can create a scrolling stock quote list, and select from more scrolling options, such as sports scores. The receiver allows you to listen to one station while you preview the programming information on others, displaying five channel numbers and names while you are searching. And, thanks to a large, legible display (up to 47% larger than the competition's), you can check out the info with a glance. The basic package includes the receiver and wireless remote. For the system to work, you will also need to order a car kit or a home kit. The kits allow you to hook the receiver up to your car or home stereo system. A subscription to XM Satellite Radio is also required. XM Satellite Radio brings you radio the way it was meant to be! With over 100 channels of digital quality music, news, sports, and entertainment for just $9.99 a month, you can enjoy programming from the brightest talents in radio. XM programming can be heard anywhere in the lower 48 states. (Service not available in Hawaii, Alaska, and U.S. Territories.)
