The XM™ Satellite Radio antenna is located on the roof of your vehicle. Keep this antenna clear of snow and ice build up for clear radio reception.
If your vehicle has a sunroof, the performance of the XM™ system may be affected if the sunroof is open.
If the rear roof rack rail is too close to the XM™ antenna or if objects stored on the roof rack cover or block the XM™ antenna, the performance of the XM™ system may be affected.
