Hi, iv just purchased a discovery 2 on an 04 plate. Its an ES Premium and has the harmon kardon,

Now the guy i bought it from owned it for 6 years and purchased it from a main dealer but when he bought it 6 yrs ago it was fitted with a jvc after market jobby, its prob had the nav unit whipped out for another car at the dealers, anyway i decided to buy the correct nav unit for the car, its the becker black single shot head unit, iv put it in today and its all powered up etc and plays the cds great, the problem i have is im left with 2 small square plugs that i cant seem to fit into the unit? The steering wheel controlls are not working and the ariel plug is to big.

Obviously the ariel is not connected so its saying no signal, on the back of the unit theres room for 3 wide plugs but iv only got 2 plugs to put into it butbyet im left with 2 small ones. Can someone tell me how its supposed to be connected up? Or maybe someone has a picture of the connectors im looking for or iv got missing, all the wires are genuine landrover loom wires etc and nothingbhas been cut,

Is the satnav ariel on the roof the same as whats used to pick up the radio stations?

Appreciate any help or advice anyone can give me.
Chers
