Compass System (U.S. model without navigation system) If this procedure is not necessary the system proceeds directly to the Compass screen (see page 286 ). During initialization, the system searches for all available GPS satellites, and obtains their orbital information. During this procedure the vehicle should be out in the open with a clear view of the sky. After 30 minutes with this screen displayed, turn off the engine and restart the vehicle. If you now see the Disclaimer screen, the GPS initialization is complete. NOTE: The average acquiring time is less than 10 minutes, but it can take as long as 45 minutes. If the system is still unable to acquire a signal, follow the instructions on the screen, or contact your local dealer for assistance. If within ten minutes the system fails to locate a sufficient number of satellites to locate your position, the screen above appears. Follow the instructions on the screen. 300
