Went very smoothly in the end. The car doesn’t have ISO plugs but when I had the Sony in there I converted it to ISO, so the aftermarket harness just plugged in and it worked fine. I did wire up the Illum signal so it dims when the headlights come on and the reversing camera comes on in reverse so result! Wireless apple airplay is very good indeed. No stuffing around it just starts the tunes and nav when the car hits accessories. It’s not the best unit you can buy but it is better than the Sony.
