The multi-band antenna is on the roof of the vehicle. The antenna is used for AM-FM radio, OnStar, the SiriusXM satellite radio service system, and GPS (Global Positioning System), if the vehicle has these features. Keep the antenna clear of obstructions for clear reception.
If the vehicle has a sunroof, and it is open, reception can also be affected.
