Its basically as David described it.
The fitment / removal of the center console panel is basically the same on the 4.5 and the 4.8.
Its secured with 2 screws as described above. Other than that the panel is clipped in.
It is actually a bit easier on the 4.8 compare to the 4.5 due to the allocation of the switches.
Try to loosen it from the bottom as per Davids pictures, You can also try to loosen it from the side. Start with the LH side . (The center console panel includes the vertical wood-trim ... its one part )
If you are relay not sure than I would suggest taking a drive out to the Zambezis Traders market.
Go to the parking at the back and have it quickly removed by Tony. He is driving a Nissan 1400 .
He can than also check out your radio unit and / or install a new one. He does radio installation 7 days a week.
