Over on the left side, there's a removable blank-off, about 8 mm x 30 mm that pops out. I think you have to add the socket on the the 3.0 as well--I have not looked at mine, instead put a always-lit led flashlight in the4 gloce box. As stupid as this sounds, I cannot locate the flashlight plug-in in the glove box. Owners manual only says it is located in the left-hand side of glove compartment. Do all vehicles come with full time, pronged cradle charger? Help!
