Sorry took me longer to get the pics than I thought.
To disassemble the Nav HU just release the 10 clips around the front bezel.
Then disconnect the ribbon cable from the front panel. (Circled in red)
Then disconnect the small ribbon cable connecting the control board from the other board. (Circled in blue)
The big board in the front panel has 1 single LED on it. While the small control board has all the LED's for the volume knob and the push buttons.
To remove the large board, remove the 4 screws and disconnect the 2 ribbon cables shown here.
To remove the the control board, remove the volume knob by pulling straight out from the bezel front. Then remove the 7 screws.
