When I reverse the car gear " R", the display cannot slide out automatically. I try to press " Open" button but nothing happened. I have to change from gear " R" to be gear " P " and then press " Open " button, the display would be slide out to show. I ever used the other car audio brand that the display can slide out automatically when the car is on the gear " R" I think the case does not comfortable for the customer. Pioneer should improve.
