Our OE Nav monitor is pointing upwards at about 25 degree angle,so any sun cover you get ,you will have to cut off from the sides ,about 25 degrees,for the cover to point forward,otherwise it will point straight up and it wont block any sun!

I am happy with the angle I cut which blocks 80% of sun,If I was to cut at 30 degrees or more,then from the driver /passenger sitting positions ,you wouldnt be able to see the top sdes of the screen!

A better alternative ,would be to remove monitor ,dismantle the back to access the tape drive motor,reverse the wires and alter the microswitch stop ,so that when you press the tape deck button,the monitor would now tilt forward!
