My Boxster already has the CarPlay option installed. As you may already know, it is a wired system. The phone must be plugged into the USB port for CarPlay to work.
Lately I’ve seen some wireless CarPlay dongles that plug into the USB port and supposedly bring wireless CarPlay support. I guess the phone connects to the dongle through Bluetooth or WiFi and the car must see it as a wired connection.
Everything I read though talks about installing some firmware on the head unit to activate CarPlay but I think this may be if you don’t already have CarPlay installed.

Has anyone tried one of these dongles just to make an existing CarPlay system wireless?
