Antenna Module (ATM) (2003-2006): Design: GPS
The data transmitted from the GPS unit consists of signals received from GPS satellites.
The GPS unit transmits the signal to the multimedia module (MMM) via the MOST network.
The navigation system requires at least three satellites in order calculate the position of the car. The position calculated from the GPS satellites is accurate to within 25 meters.
The power supply to the GPS unit is from the antenna module (ATM).
The GPS unit is integrated with the antenna module (ATM) and transmits signals via the MOST network.
NOTE:
If the GPS signal is being diagnosed because it is missing, the signal should be tested outdoors. This is because the signal may be blocked if the vehicle is indoors.
