Adding CarPlay to an older vehicle

The lack of Carplay in recent models raises the issue of data privacy. Presumably these vehicles download contacts and other data from the iPhone and use it for their own purposes:

So I can understand the desire to find aftermarket products that enable Carplay.

When renting a vehicle I now have to check that it will support wired Carplay (don’t even like the idea of a Bluetooth connection since the car has control of the data).
