An adjustable device placement system of a vehicle includes a center console bin of an armrest. A separator wall within the center console bin divides the center console bin into a first section and a second section. An aperture has notches spaced vertically along the aperture. A position mechanism is disposed within the aperture. The position mechanism includes c-channels formed along lateral sides of the position mechanism and receives sides of the separator wall that define the aperture. The position mechanism remains in direct contact with the separator wall as the position mechanism slides vertically within the aperture. The position mechanism includes tabs that extend perpendicularly away from the separator wall and teeth that enter the notches, thereby locking the position mechanism into a position. A bottom portion extends a predetermined distance away from the separator wall and toward a front wall of the center console bin.
