It's a bit fiddly..

You have to remove the top 'shade' over the info display, it 'just pulls' off, you think you're going to snap it. 4? screws for the panel with the controls on
Panel under the radio control unclips. Couple screws there.

The vents around the sides of the radio controls come off with the radio controls. Panel unclips.
Audio unit is behind there, the connector is locked in with a lever on the plug so doubt it'd be loose tbh. But worth checking.
