    Other things come to mind. When I disconnected the DCM, I did not disconnect the battery. I did have the key away from the car. Maybe if all else fails, reconnect the DCM, see if that restores the compass, then shut down the car and disconnect the DCM again and see if it sticks?

    I think it's getting closer. It seems like it's 90 degrees out of whack.
    I might take another drive after dinner, maybe do some circles counterclockwise this time.

    Driving around with the diagnostic screen on showed:
    -One, maybe two, yellow squares (Date/Time), and then disappear, but enough to snag the date/time and provide it to the dash
    -No blue squares (Position). No Lat/Lon in diagnostic screen. Which is as it should be. :)

    If it is indeed recalibrating itself, it would be nice if it could be sped up.
    What speeds it up probably is the Lat/Lon info from the head unit, which is likely unavailable because there is no hardwired GPS antenna signal getting to the head unit. Although, the head unit can still sporadically pick up the time component without an antenna.

    That's my theory.

    I've given up for now.
    I'd probably break some plastic if I went in to experiment, so I'll leave well enough alone, for the time being.

    Went back in. Restored to original. Compass works perfectly. DTC cleared. Since Toyota connect was waived, I'm gonna stick. Future trade is also a consideration.

    Anyone want the autoharness.com harness for postage?

    My harness is arriving Monday. After driving for a few days the only issue I see is that sometimes apple maps/google maps/waze does not track properly but then it will suddenly snap into place. IF the phone is connected via USBC then it works perfectly every time. I guess it tries to use the car GPS first if it is wireless carplay. I am not going back to connecting the DCM. It is worth it to just plug the usb cable in for me... Especially after seeing the LexisNexus stuff.

    My hope is that this thread serves as future reference for anyone looking to do this. It will have the howto, the pros and the cons.

    Here is the letter I received from LexisNexus today. Minimal redactions where it makes sense. I looked into their site using the provided password to download the 62 pages of information they had on me!

    Glad to see other people are taking their privacy and security seriously. Good for all of you. (y)
