Sensor Check

This screen will display information to check that all the input sensors are functioning correctly.

• Wheel sensors - These are used to calculate the vehicle speed
• GPS satellites - Displays the number of satellites visible to the system at that time
• GPS Status - Displays the number of satellites visible to the system and the GPS status There are four possibilities for the status and they are as follows
• GPS Error - Communication error between the GPS receiver and the navigation computer. This could be a system failure
• Satellite search - The system is searching for satellites. This may indicate a system failure
• Satellite contact - The system is tracking a number of satellites but does not have enough information to determine a position
• Position known - As the name suggests the system is tracking a number of satellites and has determined the vehicle position
• Gyro - The navigation computer incorporates a gyro which determines any changes in vehicle direction. In this screen it can be seen moving as the vehicle changes direction
• Direction - This sensor determines whether the vehicle is travelling forwards or backwards and will display FWD or BWD.

Exiting service mode is achieved by pressing the menu button on the control panel which returns the system to the main TV/Navigation screen.
