2016 TRD Pro does not have dedicated sunglass storage. I used a SlipToGrip Twin pack, cut to size in the little compartments in the dash, just anterior to the transfer case shifter and cup holder, to allow sunglasses and an iPod to stay in place (100x better). Sunglasses fit well in the lower compartment, and iPod Classic (I know it's old school) fits in the upper compartment. My sunglasses used to slide out of that little compartment evertime I accelerated. They stay put perfectly with the sliptogrip pad in there:
Just search "Sliptogrip" on amazon.
