To install, first the headrest is removed. The left headrest post is positioned in one of the three different sized holes on the left of the mount. The right post is located in the slot on the right of the mount. The headrest posts are then re-positioned in the seat.
This configuration of slots and holes allows the headrest mount to be attached to a huge variety of headrests, with post diameters ranging from 10-14mm.
To mount your tablet or phone, simple press the device firmly against the micro-suction tape on the back plate.
Once installed, the device bracket can be detached from the headrest rail mount. This feature gives the user the ability to store the extending portion of the mount without having to first remove the headrest.
