I don’t think there’s convincing my dealer to get into the service menu and disabling it.
I would presume that other manufacturers might have this as well.
How far do you live from Massachusetts, and how do your feel about driving vacations?
I would be very concerned that the flag just continues to submit your data but with a "telematics disabled" bit set on it. This is absolutely how location privacy is implemented in some devices. Moreover, even if it is effective it could be remotely reset including accidentally as part of an update.
Better than not setting it, I suppose! :)
You can get an Autel KM100 for under ~$400 from China. Worked great to program in a couple spare keys for my car and less than what the dealer was gonna charge...

On newer vdubs there’s both a “location services” and a “offline mode” toggle in the infotainment, though this only turns the infotainment SIM off. Obviously this also disables remotely controlling the car using the app.
And the secondary eCall SIM cannot be disabled - not without triggering a fault code and a tell-tale. Since eCall is considered a safety-critical system it has self-monitoring and must work for the vehicle to pass inspection. It even has its own separate power supply. This is true for any vehicle (type) newer than ~2018 in the EU. This probably makes tracking the rough location of any eCall-equipped vehicle quite easy, if you have signaling-level access to the cell network – exactly like in all those SS7 exploits.
edit: turns out they thought about that and eCall modules aren’t supposed to constantly stay connected to a cellular network (dormant mode). Instead they only log onto the cellular network when needed. Difficult to verify as a consumer though.
It let me disable telematics, and Kia support confirmed that my car was flagged as a "Massachusetts variant" even though it wasn't purchased in MA.
I am just going to say in the future that I am not buying car from you or recommend to anyone if you don’t disable it. Let’s see if I can get a new car some day.
- 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
The reliability is way better than GitHub's uptime.
Better even than my car's uptime.
You must work in telco.
99.9999% or it's unusable :P
At least for Subaru, the dcm also connects to all antenna so removing it disconnects gps antenna. For other cars, I'd still expect removing the dcm to be good enough for 95% of people given the current expectation from car companies that no one would want to remove the dcm.
If you log 32 bytes once per second that's only 962 MiB per year uncompressed. But 32 bytes is a lot (or depending on what you're logging not very much), once per second is almost certainly more frequent than necessary, and almost all vehicles spend the vast majority of their time turned off.
For example logging RPM every 100 ms, 8 bits gets you reasonable but not perfect accuracy and you're looking at 300 MiB per year of continuous operation. It's just not much of a storage requirement for quite detailed telemetry.
It still technically is used for telemetry... but only when you get into a wreck. It'll ping the onboard GPS at that time for coordinates, then place a voice call over your paired cellphone to 911 with TTS coordinates and information about the wreck.
