No, you don't need to use the touchscreen for that. Unlocking the charge port with the fob does release that. Also, with the charge handle thing you mention, yes, if you just quickly press and release it, very often, it will immediately re-lock. Press AND HOLD, and it will stay unlocked as you pull it out. That works for both the Tesla plug and J1772 plug. But as described, with a J1772, you will also need to use your other hand to pull the adapter out along with the J1772 handle.But don't you still need to go into the car, view the controls screen, then click on the "Unlock" section to get that adapter to unlock from the car? Or does holding the trunk button on the fob do that for you? I've even had trouble with that using the button on the connector, with it locking right back in a fraction of a second after unlocking.
