External Antenna
If your vehicle is fitted with an athermic (heat reflecting) or a heated windscreen, GPS signals to the Bluetooth GPS
Receiver are greatly reduced or blocked.
An external antenna is available to ensure that sufficient GPS signal is available. The antenna is attached by a magnet
to the outside of your vehicle, usually on the roof. The antenna cable is plugged in to the External GPS Antenna MCX
Socket. The cable may be threaded through the door opening.
The external antenna is available from your Navman retailer.
