hi all: Rear Camera and satnav..Primera 2005 s
 

hi im pally.
firstly i sorry for puting this topic in the wrong section.. i'm a new user and have restricted access...

My uncle has just brought a primera 2005 reg s model.. so it has the tv screen in there but no satnav or rear camera..

my questions are can i install the camera and satnav my self... if so where can i get these from and how much would it cost as it only has a cd player and i think satnav requires a dvd player

also would the wiring already be in the car....
any advise would be wonderful
