I've got a 2001 4.4 sport - it was fully loaded with CD changer / nav / dsp and the head unit has casette, screen, obc etc on it. I want to change this as it doesn't always work and I've got a chinese replacement that will do everything and more.

To remove the head unit there are two screws that lips under the central air vents. Getting to these screws seems impossible without causing damage to the vents so I assume the answer is to remove the vents first. I think there are some clips to press on but I really don't know how to do it.

Anyone done this?

Prize off the trim section around the screen there are 4 T10 torx drive screws, 2 Left & Right side towards the top and 2 bottom easier to get at with the screen open. Then the unit just slides out no need to touch the vents.

Hope that helps

Ooops
Try this, if you are still struggling
To remove the 4:3 screen. To do this 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 light. 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. Once the monitor is removed from the opening, unplug the two connector modules from the back of the Nav unit.

Next stage , I've got the stereo out in one piece, also removed the DSP, Bluetooth receiver, phone module etc.

There are two 12 pin connectors, one blue, the other white or black (12 pin) . Is there a diagram to say what the pins are?

Another question, I have an adaptor to plug into the radio module but with the lpg tank in the way, there does not seem any advantage of plugging this in as I'm going straight into the loudspeakers via crossovers, there is no power on the plug? The only thing I need is the aerial but even then, I may be better putting an eBay fin on the roof.
