    be done outside and away from man made structures or natural features to ensure all signals are not obstructed.

    1. Connect the Radio Diagnostic Tool (special tool #9977-6-13, Adapter, Long RF RG-58 Fakra) and (special tool #9977-6-SATXM, Antenna, Satellite/Sirius XM) to the Satellite Antenna connection on the back of the Radio.
    2. Place the test antenna base on the roof of the vehicle.
    3. Turn the ignition on.
    4. Drive the vehicle outside to an un-obstructed area.
    5. Turn the Satellite Radio on and select several different known good stations.

      Is the reception still poor or not available?
