Another cable is the FAN cable, but I can also tell you how to build one your self if you want.

 Hello,
I have been following your inspiring trend on the x7 retrofit and I'm happy to say that I just purchased my screen and Nav from ebay and can't wait to get it in. I was wondering if you could give me instructions as to how to use existing stock cables and wires as none of the units come with any connectors. I wouldn't mind even buying them but I could not find any, or don't know what I am looking for. Finally the question about coding. should i go ahead and purchase that usb device for the coding from china? is this something dealers usually carry (probably not)? There is a gentleman named Patryk who comes highly recommended on there forums as a guy who can remotely programme the car for the nav after the install. i guess i could ask him too if I need the cable for the coding. I must say being an IT guy the idea of programming my own car sounds tempting. Thanks in advance for any help.
