I had the system installed aftermarket by Quadra in Michigan.
I wanted them to put the control on the dash by the drivers left knee. They refused. Said it would stick out. In an accident, my knee could jam into it. Probably a legal thing. They ended up putting the control on a tether under the drivers seat.
I saw in another post that Bclemens said they will start putting the control in the entry way.
After a couple years of use, I like the control nearby the drivers seat. About 2 to 3 times a year, I get the warning beep for not fully retracted. It seems that at least one of the jacks crept down some. From reading various forums, it sounds like I'm not alone with this happening. With the control under my seat, I can easily / quickly grab it & hit the emergency retract button for a few seconds which solves the problem. That wouldn't be as easy if the control was further away.
Just my 2 cents...
