I am currently using a Dodge Journey so the entire setup will be different, but i stilll have the cubby hole, and it is a decent angle compared to the one in my 07 charger. Holds still while the torque slams forward.
Garage door opener since my car doesn't have the buttons on the overhead to program my garage door. Thought I'd see if this was an active topic again I would get some more ideas on what to do with that hole.
Get a universal dash kit, cut to size, secure to pocket or remove the pocket entirely, and install some cool switches that light up and do bad ass sh*t. Boom. Custom Auxiliary switch panel that looks stock. Hook up some lights, nos, a fog machine, whatever, the sky's the limit.
