Press the "band" button, and the radio will switch between AM, FM, and XM. When XM shows in the display, tune to channel 1 which will dispaly the radio ID#. Make sure the car is sitting outside with no obstruction to block the signal to the radio, leave the radio turned on, call XM, give them the radio ID#, and after about 10-20 minutes, XM Radio will be active in your car.
