Hi. I have your answer. My Montero did the same thing. 1st...With key in off position, push and hold the "DISP" button. 2...While continuing to hold down button, turn the ignition to ACC position. Keep holding the "DISP" button until you hear a beep tone which will last for about 10 secs. You should see the display "Start to check the system. Please turn the ignition key to the on position. 3...Turn ignition switch to "ON" position to start the system-connection-check. 4...Wait for approx 8 secs. The system will give a beep signal. When the connection is completed, the "completed the system connection" message will be displayed. After this, you will need to reset the compass. It will give onscreen instuctions. Hope you get it!
