It is also high on my consideration but will go with my initial plan to use my old iPhone 7 without SIM hot spotted to my iPhone 13.
My initial concern is on how it will function with the my Cardo in intercom mode as the instructions claim that you may have to switch the Bluetooth output from the C5
The C5 unit is getting good initial reactions on other boards and I have been already looking for an AMPS adapter that will allow it up mount to the Navi cradle if I end up getting a C5 CarPlay unit.

AliExpress had a cheaper version of the Winderlich part but it is no longer available.
And use a BMW part to connect to the Navi cradle socket.
