I wound up upgrading my Pioneer to the AVH-W4400NEX the other day. Obviously I haven’t had time to fully vet this, but I seem to have an issue where the XS Max disconnects from the head unit’s WiFi, thereby dropping CarPlay.
I had a wired Pioneer CarPlay unit that always seemed to have issues maintaining the connection when I would first start up the car. It was basically 50/50 if I would need to unplug and replug in the phone. Add into that the screen de-lamination that mine suffered from and I have a pretty sour taste about Pioneer radios. I grabbed the Alpine ilx-107 a few weeks ago and couldnt be happier. Wireless CarPlay picks up every time without issue.
