I have a 2023 MY AWD and I'm trying to remove the rear headrests to add some seatbelt guides. In the instructions it says to put in a flathead screw driver below the little area that pops out that allows you to extend the headrest in order to remove the headrest. However, I don't see any sort of slot on my 2023 that allows you to put a flathead in there to remove it. Has anyone been able to remove the rear headrest?
