    There is an ongoing class action lawsuit against Toyota for selling telemetry data to insurance companies which include speed, braking, gps, and voice. Honda, Acura, Kia, Hyundai, Mitsubishi, Subaru and Toyota were found to be selling this data to LexisNexis and Verisk who in turn created a score for you and sold the scores to insurance companies. GM was found to be selling on star data to insurance companies by the government.
    GM agreed not to sell your data for 5 years.

    For Toyota you can disconnect your car in a few ways:
    1. remove the DCM module
    2. pull the fuse for the DCM module
    both will cause the bluetooth speaker not to work and throw an error on the dash. Nothing else will be impacted
    3. Only via the Toyota app, you can disconnect all connected services- this will disable the safety connect crash detection and automatic call for help, web based map, remote key, and any visibility to car info from the app. It will NOT affect SiriusXM, Carplay, or any regular driving functions.

    I disconnected the connected services. The surprise is that ALL the car settings reset. Radio station favorites, door lock settings, automated seat adjust settings, light timer settings. Makes you wonder why all this crap is connected remotely and what Toyota is doing with it.

    BMW pledges never to sell personal or telemetry data without express user consent.

    Toyota makes it pretty difficult to opt out of its automatic opt in. You NEED to do it with the app. Once in the app you go to your account and then privacy. It also has links for you to request hard copies of all the tracking info they have on you, request the data get deleted, and request that they do not sell your data. I made all three requests. I received an email today pictured below. Toyota is no longer selling my personal information. Note, you can make these requests without disconnecting Toyota Connect but who knows how the terms will change in the future.

    This is not a matter about being a bad driver. Why should these companies be allowed to harvest telemetry and sell it? Unless you use their subscripton map, want that piece of mind of some service detecting when you are in a crash, or want the app for a digital key or maintenance reminder I strongly recommend giving Toyota the finger and disconnecting.

    Yes exactly. Cost of doing business. This makes me want to pull the fuse on the DCM altogether

    Here's a video explaining how to disable and remove the DCM on several brands

    I have a harness but have not installed it. Maybe this summer.
    I forget: with the harness do you lose any capabilities, re: speaker and the like? I think not, but don't remember.
    edit: Watched the video. You got me re-motivated.

    It was not in early 2017 Gen 4 Prius Two. Since it had some connectivity, it may have been in the Prime though.

    They also spam you with emails including the boilerplate to opt out of marketing emails. If you do that, they continue sending the emails with the same boilerplate but call the emails something else Calling Toyota they say you cannot opt out of them I send them to SPAM.

    Another danger of that data is that Toyota is still experimenting with features and regularly provide incorrect information and false warnings. If you use their navigation, the speed limit detection WILL be incorrect because it uses the incorrect navigation data rather than the actual signs. Without navigation, it will still sometimes bne incorrect. It detects speed limits for school zones and construction but does not recognize if the school zone is active. It also does not detect end of school zone, end of construction, or end of speed limit signs.

    I have had it warn of a collision when no danger was imminent.

    What makes you think that Apple and Google (your cell phone) aren't doing the same???? How do you think those targeted ads are getting into your mailbox or SMS???
    While EU privacy rights are the most stringent in the world today, that doesn't mean that data isn't stored someplace. They just can't sell the information - wink, wink, nod, nod..try back-tracing where that data came from?......... Opt-out or not..... That's the reality of it. Pull the transmission module is the only way to be sure - even then; every-time you pair your phone; could that information be sent through it??

    you can leave your cell at home or put iphones into lockdown mode. Again, what gives Toyota the right to do this? irrespective of the other companies.

    Your phone may have your location, but not the telematic details your car possesses.

    Ahhh; simplistic approach.. Ever wonder why a simple metric conversion app needs access to your contact list, camera and other phone sensors. When was the last time you went over your permissions on each app on your phone???? I've deleted apps for less; but if you want to use it - most will lock-up if you remove those permissions. The price of free use. You can also NOT drive a Toyota, if it irks you that much; but other automobile vendors do the same.o_O Your just not aware of it. There are Tesla's in eastern Europe, driving around under the previous USA owner's Sirus XM account. Wrecked here and glued back together there......

    YMMV.....

    Ok the video actually makes this waaay more complicated. It is very easy. Skill level 2-3 out of 10.

    1. remove the plastic piece that straddles the center console to give room to remove the center console.
    upload_2026-5-31_15-11-16.png

    2. remove the center console. It just has clips holding it down. It pops straight up with a gentle pry tool.

    There are 5 plugs if I remember... might be 6: 3 across the front, 1 under the parking brake area, and one at the way back by the hinged compartment. Start at the back by the hinged compartment and then work your way forward because the harness does not have a lot of play under the radio and you need to rotate the console up to access the front plugs

    upload_2026-5-31_15-14-13.png

    4. Unplug the white connector under the DCM

    upload_2026-5-31_14-45-58.png

    4. reach up under the radio area and unscrew the 2 10mm nuts holding the DCM in place

    upload_2026-5-31_14-44-7.png

    5. with a little manuvering the DCM can be rotated out:
    upload_2026-5-31_14-44-57.png

    6. unplug the connectors from the DCM. I decided to leave the three connectors plugged in as I would just not plug the white conector back in from step 4.

    upload_2026-5-31_14-47-10.png

    7. reinstall the DCM

    8. I ziptied the white connector so it was not flopping around

    upload_2026-5-31_14-48-9.png

    Now to access the cable:

    1. remove the OBDII panel under in driver foot well

    upload_2026-5-31_15-14-56.png

    2. remove the side panel in driver foot well (it is overlapped by OBDII panel)

    upload_2026-5-31_15-15-18.png

    3. Access the cables from the DCM. peekaboo

    upload_2026-5-31_14-49-44.png


    upload_2026-5-31_14-50-1.png


    Everything ia back together except for the OBDII panel and driver foot well panel as I wait for the cable. The U-shaped panel and center console are the only other two things that needed to be removed or installed.

    *****One strange error******

    I have to diagnose why the cruise control is being reported as manfunctioning. I do not think it has anything to do with the DCM and there is nothing on the center console related it to. I am going to dig into that now. There are no other errors on the dash, it MIGHT be the way toyota indicates there is a bad DCM. If this is the case when I get the harness it should clear it up. I might not worry too mich about the reported malfunction until I get that harness and see if it is still there after connecting it.

    UPDATE: I started up the car again to see if there were any apply carplay issues. Now there are no errors on the dash. Cruise cotnrol seems fine. No warning that the DCM is even disabled. All good. I am sure the bluetooth mic is disabled as that is a known issue the harness solves. Carplay has no issues.
