Older Toyotas also had a DCM fuse, and this was the easiest way to get rid of telemetry. I am not sure if partially disassembling the dash and physically removing the DCM is now necessary.

There's still a fuse for the DCM even in this car but:

- It has an internal battery and will keep running for quite a while after pulling the fuse. This is a safety feature in case you get in a crash that disconnects the 12V battery

- It will break your in-car microphone as discussed. Repairing that requires opening up the dash

- That won't do anything for disconnecting the GPS antenna

GPS is receive only. If you've disabled the ability to send telemetry, there should be no reason to be concerned about the GPS antenna.

If it keeps collecting telemetry it could upload it later if it ever gets the chance. Better it isn't collected in the first place.

That also means it isn't passed to your phone via android auto / carplay. Phone GPS is much worse than car GPS for road navigation. It's basically unusable.

Good point, but in practice I think the only way onboard data could be exfiltrated is by a dealer while the car is being serviced. If you DIY or hire an independent mechanic, this seems unlikely.

Or by the FBI, NSA, CIA, DHS, or some other interested entity.

		If a TLA is interested in you then you don't need to worry about a data log in your car.
