I used to leave mine in the drivers door, but it fell out one time when the door was open, and I almost drove away without it. Since then, it is in the center console.
mine stays at the driver side door. looking for a better way to secure it due to the noise it creates when it moves.
I wonder if there is a similar product that fits the new center console in 2021 models. You can find several tray for the new center console in Amazon but none of them seem to have a place to hold the J1772 adapter.
