I saw this on reddit and am contaplating purchasing a toyota and I would say you can code the modem out from the techstream 2 day rental. The grounding antenna thing is not required, but its an easy DIY tool and just interesting in general as I was making a "mod" list of what to do if I were to purchase.

With the coding from techstram you can also modify the Denso Headunit programming to not do telemetrics via cellular bluetooth connection.

You can also have block the connection on the phone if you run a custom DNS server.
