I was really struggling on where to mount the 2-step box for easy access when needed and for non visibility. I found the best place to mount it was behind the glovebox on the bottom/left side. The problem is that the box is too tall for the glovebox door to even think about closing. I carefully removed the circuit board and decided to cut the box down to half of its original height (after consulting with Bob). Once I did the the box fit easily with velcro to the back of the glove box. Now I have EASY access (if needed) and a very clean look. I'm certain that the top will go on however I am not going to put it on since it is in the car and not in harms way. The box works GREAT and if anyone is on the fence about buying one, don't be. Bob was very helpful with answering questions if I had any concerns. Thanks Bob for a fantastic product!!
