sorry i see what you are trying to do now
but i think you need to see the head unit and its connectors as adding the factory usb may not be possible
the factory usb works through a module and sends data to to head unit and then the screen
and you are getting rid of the factory cd400 and display so this may not work
plus the usb connector for the factory module is for input use for a device
so join that to the usb input for the new headunit
and then where will your input usb be for you phone etc.
may be i am not understanding you correctly
can you show me what unit you are getting is it a gen 2
then i can see what you are trying to do
