Narrow Navigation Screen Removal

The vent above the NAV screen is first removed. There are two clips built into the bottom of the vent opening pressing down towards the top of the NAV unit. These are located 4 slots from the left and right, respectively. Insert a very small, flat bladed screwdriver into the center bottom slot of the vent. You will see the clip or retainer in the lower surface the vent. Insert the screwdriver into the edge of the clip and lift slightly. Now gently pull w/ wiggle the vent outward. Repeat on the other clip until the vent is free.

Next there are two Phillips screws on the top left and top right of the nav unit located behind a felt cover. Remove the felt cover and then remove the two Phillips screws.

Finally, remove the rotary button on the Nav screen that is on the right. Insert a small screwdriver into the aperture and turn it approximately 45 degree counter-clockwise to unlock the Nav monitor.

The NAV head unit should now just lift right out.
