My CX-5 is quite slow to connect with CarPlay, but it works (MZD Connect system).
My CX-5 was always a bit slow to connect but it would always eventually connect until I got the car serviced in late 2021 and since then it's intermittently failed to connect altogether. It seems to be totally random.
They must have installed a software update during that service and consequently broken it.
