An electronic device holder includes a mounting surface configured to receive and retain an electronic device. First and second doors are disposed on opposite sides of the mounting surface and are gearingly engaged to one another on a rear side of the mounting surface for synchronized lateral movement between open and closed positions. An actuator is disposed on either the first or second door for actuating the doors to the open position from the closed position. A detent lever is pivotally coupled to either the first or second door and is configured to detent the doors in the open position. A detent release lever is pivotally coupled to the mounting surface, and is configured to release the detent lever such that the doors automatically move from the open position to the closed position.
