Look in the menu I think it’s under car settings or something like that, find mirrors and alter the fold mirror setting by removing the cross. The joystick is the “enter” button.
This. It depends on the year of your car, as you can change the fold settings in the Car Settings menu in the later cars. But if you can’t see the option I’m afraid it’s a trip to a MD or AM specialist to hook it up to AMDS. BRM.
