I have a Sony XAV-AX100 installed in my S5. It fits perfectly and has Apple CarPlay.

The installation was done by Krazy Horse in Bury St Edmunds when I bought the car earlier this year. They have fitted this to several cars now and it looks like it was there from day 1. The only feature missing is DAB but with CarPlay I can stream any radio stations I want to listen to. The Sony microphone is installed on the steering wheel cowl. I cut down the foot with a Dremel so it would fit into the gap where one of the screws holding the cowl is located to hide it as much as possible.
I am now contemplating one of the aftermarket wireless CarPlay adaptors to save me plugging it in every time I get in the car.
