the little 1/2 din facia you need is also available from autobarn 
 
if you have the premium stock stereo I would advise not using the existing speaker wire in the car, I would run new stuff, a lot of the premium set ups have extra amps/ equalisers hidden in hard to reach spots, its easer to just bypass it all,
 
(I'm not sure if the land rover stereo does or doesn't have extra amps, just past experience)
