A 2 mm allen wrench is required. Remove the 2 allen screws on the face of the blank, pull the face directly off and place the face in the button hole. Align the back portion with the face and press them together. Replace the allen screws and tighten.
Removal of the vehicle trim piece is recommended for install as access to the back of the piece is necessary. There are plenty of guides on the internet for removal and replacement of the trim pieces. If you have any questions about install, feel free to contact Niche Motoring for help.
The ports on the back are the same as on the front. Two "A Female" USB ports and one 3.5 mm AUX jack. We recommend MonoPrice for all your cabling needs.
