Hi all and greetings from Melbourne Australia!
I happened to find your forum by sheer luck and I must say that I am glad that you guys have been discussing and planning modifications regarding the IQ unit as I too have been involved in the sort via our Aussie forums.
The fact that you've been able to obtain the components for the video plug Tom has been a great win as I have fallen short of accomplishing such feat myself after trying to source them direct from SMK!
Just a bit of background from myself, I currently own a VE Calais V which is the shorter wheel base version of the Caprice which you have over there in the States which comes equipped with the IQ headunit.
Unfortunately, my vehicle lacked the rear roof DVD components due to apparent cost cutting measures which I found painful as I really wanted to have that setup.
I set upon a challenge to install the rear roof DVD and associated components myself which, thankfully, after a lot of research and personal development I was able to accomplish!
I was fortunate enough to have the video connector already due to the factory installation of the rear view camera.
I now wish to experiment further with the IQ unit however I am in need of the video connector components in order to do this!
Is this something you guys are able to assist with?
Also, if there is anything you require some guidance on feel free to ask, I'm more than happy to help where I can
