Yes -I would check the fuses first when any electrical problem happens -cheers Denny

Are you check fuses? and harnesses connections.

Try disconnecting the 'negative' battery cable...wait a few minutes, reconnect, and try again.

Did you ever find a solution for the QX56 nav screen? Mine is doing the same, I have been told it is navigation unit or possibly the screen. Was wondering if you had any luck before I pay money for something that doesnt fix the problem. Thanks

YOU HAVE A MODULE PROBLEM THAT IS SHORTING OUT AND TRIGGERING ACCESSORIES CIRCUIT HAVE IT CHECK ''CAN SHORT CIRCUIT AND CAUSE FIRE''

I would recomend looking behind the left access cover in the trunk where the navigation computer is located. Inspect the area for any water intrusion, and if possible check the connections to the navigation computer for water or corrossion. the display colors are generated by the navigation computer via RGB lines. If the nav computer is cutting out, that would explain why a battery reset helps restore the picture.

The same thing happens with my 2005 Jeep.

It was not replaced correctly, more info needed..
