Scania R series stereos

I’ve bought myself a new clarion DAB stereo to fit in my Scania.
Upon taking the old stereo out I’ve found there’s 3 plugs,
1- power wires
2- speaker wires
3- Bluetooth wiring.
On the new clarion stereo which I bought from a Scania dealership only has 2 plugs,none for the Bluetooth connections which I want to keep as it works all through the dashboard and my microphone in the seat.
I bought the correct wiring from Scania to work the stereo controls off the steering wheel but there is still no where to connect the phone control plug into.
Considering I bought this from a Scania dealer and it’s in there approved catalogue I feel cheated out of nearly £350!
Has anybody any ideas how I can wire the stereo up so I can still work my phone off the steering wheel and dashboard display please?

I see you have posted this in stereo also, as I have. :smiley:
