NON NAV System update to NAV System Possable

[David_27]

Afternoon All,
 
I’m After some Help.
 
ive recently bought a 2004 5 Series E61 and it came with the HIFI  System and a CD player  No Sat Nav and the small Screen,
 
i would like to upgrade it to the CIC System with i need some new parts for 
 
1 x Controller Pro Nav System
 
1 8ich Screen
 
+ new I drive a Wire for the Screen and GPS
 
plus it will need to be programmed ive been told
 
from my old system it looks the Main wiring harness is different to one with the SAT Nav so would i need to get a new main wiring Harness for it to work?
 
ive attached 1 picture 1 showing the back on mine,
 
if someone could tell me what i need that would be Awsome

Cheers

David
