http://www.brodit.com/They don't make a cradle with the cable included
but they do make a vast array of cradles that are specifically designed to take various makes of cables in..
According to the instructions you install the cable into the holder, securing it with a grub screw, then install the holder to the car and then you can just insert and remove your iPod.
Oh, yes - all of their cradles are 'universal' - you then buy the 'mount' to attach it to the specific car. For example they make four mounts for a facelift LHD Omega (two go by the stereo, two go by the handbrake area)..
You'll see the search box on their website, anyway
