The slot above the glove box is for the Ford installed lighting. I'll grab a pic tonight to show it if you want.
The spot in front of the shifter is a waste. I like the 3d printed idea mentioned above, or some other useful object. I tried putting my sunglasses in there, and no dice. They don't fit right, and fall out first corner I get to. My wallet is in my pocket. And I was considering making some attachment thing to bolt in there for an AP later, or my phone.
My Air Lift controller sits in the dip with the 12v socket, and I put my phone there sometimes too.
