Several comments made by CEO Elon Musk since the launch of its AP 2.0 hardware suite in all Tesla vehicles made since October 2016 indicate that the company might have to update its onboard computer in order to achieve the fully self-driving capability that it has been promising to customers.
Now it looks like Tesla might have to also offer computer retrofits for AP 2.5 cars.
It seems like the actual key fob also uses Bluetooth since September 2016 (see Electrek’s post about this), so I assume both the S and the X have the appropriate antennas to power using the phone as the key.

The people I dealt with were all very pleasant and responsive.»
