We bought a second-hand 2021 Highlander and thus did not sign any contract allowing our family to be tracked by Toyota. I went on a hunt recently for information on neutering the DCM but have thus far only found speculation and contradictory info.
Yeah it's bad out there. Don't do what the yahoos hacking up their harnesses have done. The Toyota DCM I'm familiar with has 3 coax antenna lines coming in. The outer 2 are cell and the inner is GPS. Pull the cell antenna cables out of the DCM and you should be good to go. Best to hunt down your vehicle's service manual and verify the procedure first.
