For anyone else interested in doing this mod, I managed to finish this 90% and I just saw this mod earlier today.
I don't have any during pics, but I can give you a step by step that literally cost me nothing.
1) Remove Cubby/air vent dash piece
2) remove cubby from that entire piece so you just have the box and door
3) take the door off (super easy, just take off the snap rings and pins from hinge/spring assembly)
4) I dremmel'd down the left and right pieces of the box (where the back of the iPad touches) just to make sure I had more clearance for wires.
5) Using the cutting wheel, I cut the very lip of the box, where the aux and power cables go underneath the leather trim piece. I also had to break off 1 clip that holds the air vents in so the aux cable would clear, really not an issue since a screw goes right next to it.
6) put the ipad in, and screwed everything into place. the wires do require some stripping/finnageling to clear the vent housings, but it eventually went together very snug.
7) slap it all back together on the dash, and I ran both cables down the passenger side, and they came out right under the knee pad.
I'll eventually use some black foam filler and sandpaper to fix the gaps around the side, but the cables hold it in pretty snug, so i'm not in a huge rush to epoxy and filler it in. As you can see I run the stock radio for now, so the aux input can go to the ipad, or you can plug it into something else when you're not using it.
Using the wifi hotspot on my phone I get google maps, google play music, and chrome. It's an awesome setup and definitely worth $240 and an hour of work. Best part is, all of this is reversible and you'd never know it was there.
