The XM Commander is another great way to get XM Radio in any car with an FM stereo. This affordable package has everything you need: a tuner box with FM modulator, dash-mountable display/controller, and XM's unobtrusive, roof-mount micro-antenna. The compact display is ideal for vehicles with limited dash space, yet it boasts an easy-to-read, 2-line, 32-character display. The tuner box is much smaller than most tuners, so it'll fit under your seat easily. The tuner's built-in FM modulator reduces the number of boxes you need to install by one (or you can plug the tuner into your receiver's auxiliary input, if it has one). The rotary controller and wireless remote help you channel surf. And TuneSelect™ alerts you when any of 15 songs you've saved is playing.
