Cd400 to nav500 upgrade.

[woutfab]

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!!
