Antenna
This vehicle is equipped with a fixed mast radio antenna mounted on the right front fender. The antenna cable has 2 parts. The antenna upper cable is included as part of the antenna base. The lead-in cable connects the radio to the upper cable. The 2 cables connect behind the glove compartment.

The satellite antenna (if equipped) consists of a satellite antenna cable and a roof-mounted satellite antenna.

Speakers
All vehicles are equipped with 4 radio speakers mounted in the doors. Audio signals are sent to the speakers from the audio unit, in the form of AC voltage signals.

The subwoofer is mounted behind the rear seat (Explorer Sport Trac), or behind the RH rear quarter trim panel (Explorer, Mountaineer). When the audio unit is powered up, an enable signal is sent to the subwoofer amplifier. The subwoofer amplifier then sends audio signals to the subwoofer speaker, in the form of AC voltage signals.

Navigation System
The navigation system is integral to the audio unit. The audio unit controls the operation of the navigation system and the audio system. The system uses a global positioning system (GPS) antenna, a vehicle speed input, and other sensor information to accurately establish the vehicle position. The audio unit provides the visual and audible instructions of the maneuvers required to arrive at the pre-entered destination. An audible switch feedback is provided to confirm if an audio unit button or a screen button is pressed. The audible switch feedback can be set to ALL, TOUCH SCREEN, or NONE depending on user preference.
