Audio help please - Kenwood out -- RCD 510 in .... Connections and code ?

[Steve in crete]

Hi Guys,
Greetings from Crete, you have all been a great help in the past, hope you can advise this time around ?
Have taken out a Kenwood satnav unit and bought a RCD 510 to go in its place.
Connections -- have stripped away all the jap stuff to the OEM multi pin connector, no problem with that and the unit fired up ok.
I then have two extra cables paired together with a single white and light brown connector that look original and could be the co ax Radio ariel connections ?  But the RCD has a white double
socket, one of these might fit but not both, could the unit that was in originally have two separate sockets ?  Where do I go from here ?
Can't open the unit, I don't have a code, does anyone know how to get it, asked at a dealer and got a load of gobbledygook, I bought the unit and have the serial and vin number of the car it came from ?
Thanks

Thanks Neiller that solves one problem, will get one on order and get it shipped out to me.
Now just the question of the security code any advise on that one ?
Should it be possible to get it off a more user friendly dealer ?
Thanks   Steve
