No one ever replied @johnnybb2000 and in the end I got one of these second user off of EBay
Kenwood Dmx7017dabs And Kenwood drv-n520 Dash Cam
The unit worked well and I would also advise looking at the Connects2 website https://connects2.com/ for the interconnects, steering wheel controls, as I bought some cheaper ones off of EBay and wasted a lot of time never getting them to work.
I could never get the DAB to work properly and again I think that was to do with the connections as you need some Fakra to DIN type connector as well for the aerial, there's not a huge amount of space to work with unless you take the whole Dash off which I wasn't prepared to do !! Good luck.
PS I don't have the car anymore
