I assume the factory AA/CP parts are required for this to work, however would be curious if this tool can work without the hardware.Which MZD Firmware version is required for this adapter? If FW 70 is required, which I assume, is the new usb hub + cables also required? (might be installed at newer cars from factory). In the video above the new usb hub is installed (white icon at top usb slot). So probably Mazdas original AA/CP has to be installed already to use this adapter, right?
I should have read properly & now can answer my own question. The vendor states: "Convert your factory CarPlay to wireless and skip plugging in your phone when you get in!" ... so the pre-requisite for the adapter is an original AA/CP from Mazda - with the white marked top USB slot at the usb hub.
