How is the tv/nav screen removed ?

[g.farrell]

Hi all, I want to install a parrot bluetooth phone kit to my early 2003 Range Rover. On other vehicles, normally a special little harness is purchased for the parrot and plugged into back of stereo, so I am guessing its the same for the Range Rover, however how do i remove the Stereo/Tv from the dash. I was thinking top part of dash has to be removed via screws on the top of it and the two hidden ones behind vents at sides, is there any other hidden screws/clips I need to know about to get this dash top off or is this approach totally incorrect. Please help/advise
Many thanks
