So I put this thing in a couple weeks ago. Pretty simple, had to cut the original glovebox door off. It didn't flush right out with the bottom or anything but it's covered and still functions. You'd never know the old glovebox was even there. I used their foam sealer stuff on the two sides and black caulked the top that lays on the dash. Nothing on the bottom, if water does get in I want it to come out. No pics yet as I ordered a USB charger from Amazon, had to be green backlit. Didn't check beforehand but it's coming from China and is taking forever to get here.
Here it is. Had to take my little Hulk dude off to install it but found a place to put him back on. You can see the glovebox inside the glovebox, quite a bit of storage actually. USB charger was a big a$$ hole to drill in the dash but I had to have it, used to have a RAM mount there so I just put the screws back in instead of filling holes. All of it was a pretty easy install.
Haven't ridden it yet but so far it looks like the best option out there for adding a tablet in a P5. It's out of the way and serves two purposes. Seems to be several manufacturers but props to whoever came up with this idea originally.
