Here's how to remove the audio unit:
Remove the plastic cover under the audio face. Just above the Climate contol panes. Use a flat nose pliers to grab on to the middle rib and tug downwards.
Used a rag between the pliers jaws so that the rib doesn't get marked.
Remove the two torx bit screws.
Pull out the audio unit by giving it a good tug outwards from the bottom. It should clip out. Be careful with the top section the clips are a bit stubborn. Note that the audio unit and centre vents come out as one piece.
Remove the connector to the audio unit fascia.
The main unit (which I call the CD /amp unit) can be removed. I'm not sure if this is the amp or if there is/are other amp/s elsewhere in the vehicle??
This is the back of the display/nav unit.
