P38 Sat Nav

I have a 1999 P38 Range Rover, I am wanting to retro fit a sav nav system to my vehicle, can anyone help me with what I need to get, where i could get it from and how difficult or easy it is to do, bearing in mind I am not mechanically minded. Thank you in advance.

Your best bet would be to ask on a forum with a lot more activity than this one. Try http://rangerovers.net/forums and select the 4.0/4.6/P38A forum.
