excellent, glad to hear

Does RCS work reliably on Graphene? I thought Google was fucking with RCS quietly for those on custom ROMs or other things.

i did not know about that, thanks so much!

Sorry to be the one but the privacy and freedom issue is independent of powertrain. Some earlier models before the automakers went upmarket with EVs were perfectly normal. Now the tablet-on-dash, telematics and other data collection has become pervasive in EVs but now it’s in full-force on ICE vehicles for quite some time. A Mach E and Colorado can both be, and have been, bricked by a bad OTA update.

Practicality though also will vary. If people were used to charging at home all the time, telling people that they have to visit a business to refuel every X days or Y miles would seem odd just because it’s quite different than people think is normal.

There’s no easy one-stop solution since it can vary widely.

I would look at subreddits (yuck, reddit!), or dedicated forums for your model if they exist, you’d probably be surprised what’s out there. (Example, there’s Piloteers (Honda Pilot), Kia-Forums (Kia), 4Runners and Toyota-4Runner, etc. But information may be scattered.

First objective is figuring out if it’s even on your vehicle or applicable. Older 3G radios are done since the networks that connected to them are gone now. My '16 Kia had no cellular radio. Maybe you have an SOS button or they advertise a phone app to control your vehicle remotely?

Edit: And if you can’t find specific model/year information for your vehicle, you can look for information for related vehicles and see if it’s relevant. Ex: Honda Passport, Pilot, Ridgeline sharing a lot of engineering.

in this case that’s Toyota specific and it means likely loss of phone calls on the go (but nothing else) even though the data can’t leave your vehicle anymore. It all depends on how they wire up the system. Maybe it’s easier, maybe it’s tied to something random.

The antennae only likely won’t reduce range enough. Check for an opt-out procedure prior to purchase since that’s easiest, then look for what fuse powers the connection (also easy), but worse case, lay eyes on the module itself and evaluate.

I’m sure it varies widely. In Toyota’s you can call in to disconnect (I did it while waiting for a tire pressure machine) but to do it physically you pull a single fuse and the trade off is losing the microphone.

Others have pulled the dash and disconnected antennae but it just reduces the range of the box since it’s a cellular radio like a phone.

In Toyota’s there’s a red sticker on the dash talking about it and how to opt-out. (or at least I’ve seen it in a rental and a new car - but it might also be yanked by dealer’s PDI)

Varies widely. In Toyota’s you call via the SOS button, have your VIN and they can do it. There are also other direct ways like pulling the Mayday fuse to disconnect the “Data Connection Module” (DCM) but that takes the microphone with it.

Some older vehicles that have 3G radios might not have been disconnected explicitly but are as good as dead because 3G as they knew it is gone.

It does not report via Android Auto since these vehicles have their own cellular radios, but not to say Google has its own metrics.

Your best bet is looking for a car/make-specific forum or subreddit and see if anyone’s asked the questions before while ignoring the “nothing to hide, you have a phone lol” clowns.

I ditched it after it dropped the operators like quotes, “OR”, “AND”, and “-” which hampers it’s usefulness to me.
