Hey! A fellow Mazda owner! As I’m sure you know, if you did the OEM CarPlay retrofit, it consists of the USB hub and a few extra wires and the software update. I’ve found a few products online that take the USB hub and add wireless CarPlay to it! I installed one of those hubs in my 2017 Mazda 3, it is so nice! Let me know if you’re interested in the link! If you already have CarPlay, it’s a manner of replacing the hub, which is easy.
I’d be interested in that! I’d love wireless CarPlay in my 3.
