I think while the topic is up it’ll be fun mentioning that the Colorado/Canyon does not have a physical headlight control anymore - in favor of defaulting to Auto and touchscreen controls and the project lead(?) claimed that the system was 100% bug-free.
Also later there was a bug with some OTA update for that model that’ll kill the battery.
Anyways, I bought a 4Runner and immediately called to disable its cellular radio. (dubbed DCM in Toyota-land)
How do you disable the DCM?
There have been some experimentation but the best (IMO) option is hitting the SOS button to call and navigating the phone menu to get to a representative, not emergency services and having them disconnect your car. You may need your VIN, you’ll need to confirm that you do not want connected services and it may take a day or so to take effect. Now, my SOS button doesn’t have the green light and while the radio - according to the infotainment - is still powered, it is no longer connected to the network.
Another way if you don’t plan on using the microphone (like for calls) you can pull the DCM fuse but I prefer the above option.
