Antenna - Navigation: Operation
WARNING: This page is about a different car, the 2004 Chrysler Pacifica. However, it is still accessible from the selected car via links, so may be relevant.
The navigation antenna receives signals from orbiting satellites and sends these signals to the navigation unit located in the rear of the vehicle. The navigation antenna must have open space in which to operate, items placed over the antenna, parking inside etc. can have an effect on the antenna's ability to receive signals.
