Cd400 to nav500 upgrade.

[THEHITMAN]

hi there! I'm new on this forum, living in the Netherlands and searching for info for replacing my CD400 system for a
NAVI600 system. My Astra J Sports Tourer already has the bluetooth module; Besides this it only has the AUX 
input for 3.5mm audio plugs. I already have the complete NAVI600 system (UCU unit, display unit, control unit,
USB - SD card module - see pictures). The UCU unit is already unlocked so it should be accepted after installation.
Problem which I have now are:
1 - not having GVIF cable which is the video cable which connects the display to the UCU unit (blue connectors)
2 - not having the USB cable to connect USB module to UCU unit
3 - not having cable to connect SC card / 3.5 input jack to UCU unit
Could somebody tell me where I can get these cables?? Other question I have is about wiring: the guy who 
unlocked my UCU control unit told me that I have to make some small changes in the wiring system; does 
anyone knows if thats correct and if yes could you tell me what I need to change in the wiring?? Hope one of
you can help me out with these questions; really appriciated!!

The GVIF cable is part number 95353437

The USB connect into the SD port mini-b to mini-b link 

SD to Radio Mini-A to Mini-B 

Yes there are wiring changes needed.

Hi guys, I have a 2011 Elite with a basic CD400 in it.
What would be needed to upgrade to have a satnav?
I've seen 500, 600, 650 & 950 kits advertised but I'm not sure if they would be compatible.

As to what is needed depends on the navi unit yo go for.
500/650/950, Screen + surround, main unit, control panel, USB tray and port

600/900 Screen + surround, main unit, control panel, Tray for SD port USB/AUX port plus the ports.

Wiring changes GPS aerial, then it needs programming.

So what's the easiest changeover then, NAV500?
Does the 500 need the aerial as well and need programmed?
