Hi,
Don't know if you have sorted a new head unit? but I have just done mine, took my pioneer double din unit out of my old car and put it in my new RCZ,
The unit is a SPH-DA130 DAB, has Apple CarPlay or Android Auto, bought frame adaptor which is gloss black and matches well and lead from eBay as below, frame was £66 but leads were £124, a little expensive but these get matched to the head unit and the car, still keep stalk controls, still get in to menu using the stalk and still get the parking sensor front and back,
I think it looks very up to date and modern now, have fitted a short usb cable that come out under the ash tray,
Hope this helps
