Interestingly, despite the bespoke look of these connectors, they are just USB mini B leads with keyed housings.
You can get almost any USB mini B lead and use a knife to trim the lead housing rubber to suit.

The R-Link touch screen connects to a box that does all of the work like radio modulation.
It's screwed behind the dashboard just behind the touchscreen.

The pin out connections for this unit can be found here.
