As far as I can tell, the car itself doesn't have a mechanism for transmitting data. It just stores the data.
Transmitting only happens if/when someone gets some Berla "vehicle forensics" hardware and physically connects it to the car. The Berla equipment would do the transmitting.
From the complaint linked to by The Register[1]:
> 26. Third party Berla Corporation (“Berla”), based in Annapolis, Maryland, manufactures equipment (hardware and software) capable of extracting stored text messages from infotainment systems in Honda vehicles.
> 27. Berla also manufactures equipment capable of extracting stored call logs from infotainment systems in Honda vehicles.
> 28. Honda infotainment systems thereby transmit stored text messages and call logs to Berla.
And from Berla's web site[2]:
> An acquisition may require systems to be removed from a vehicle and disassembled or be performed in place in a vehicle. In either case, acquisition hardware must be attached to the vehicle or system to acquire data.
