OK so I see the snap in 18 pin plug and only see one RF connector there, unless that one that looks like a bowden cable is in fact a screw down RF connector in which case you have two.

It is your choice whether you use that RF cable for the GSM antenna coupler in the snap-in cradle, or if you use it for the BT antenna.

If the former, you will need a second RF cable for the BT. Short ones are available for trunk mounted BT antenna, and long ones if you want to fit the BT antenna up front for a better signal strength.

The cream coloured FAKRA looks like the black and violet FAKRA, except it is cream coloured and has a different mechanical keying.
