Navigation System: Service Precautions

Service Precautions
- Before disconnecting the battery, write down the frequencies for the radio's preset buttons.
- After servicing, park the vehicle in an area where the GPS satellite signals will be unobstructed, and check the satellite mark on the display.
- When the battery is disconnected, the clock is reset to "0:00". The clock will reset to the correct time after the system receives the GPS satellite signals.
- After reconnecting the battery, you have to wait to get the initial signal from the satellite. It will take about ten minutes.
