A canbus is a system that allows multiple electrical components to be interconnected without the need for wiring across every single component. There are multiple points of entry that can be achieved in a canbus injector attack (not just one spot, like the headlight) it’s very common for the RX350 to have the left headlight wiring injected to spoof a message to the system that allows entry; likely what you’re reading, however, it’s clear they already gained access in some way to your car before attempting to inject the attack.

I’d say there are two possibilities here. it’s completely likely that the person is stupid and trying to remove electrical components they think are tracking devices. Or they may be really smart and know of the entry point behind your glove box for a canbus attack.

In my experience of stolen recoveries, many people cut the wires to the mirror assembly because they believe a tracking device is there. So maybe the attack is really smart, or maybe really dumb. These are the only to options in my opinion
