It's easy. Remove the dash top piece- you should be able to pop it up by hand (grip it and rip it method), or use a flathead screwdriver. Then, grab the mesh net at the bottom of the center stack, and pull that out.
From there, you'll need a 7mm socket (deep)- remove the 2 screws at the top and 2 at the bottom of the dash piece. Then, pull the entire dash piece towards you. Not too far, as your HVAC controls are on there. There are 4 tabs that hold it in- get those out.
Then, take your 7mm socket and remove the 4 screws for the radio. Remove the connector and antenna plug at the back.
This all is how it was done on 2007-2010 JK's. I can't promise it'll be the same on the pretty Wrangler (2011), but it shouldn't be MUCH different. I honestly haven't even seen one yet. Nor can I promise that the CANBus speed will be the same.
I can promise that before the Bluetooth or satellite radio will work, you'll need to have it reflashed at a dealership. Keep the sales codes (RSP and RSC, if I remember correctly, but CHECK THAT- it's on the instruction sheets) handy, and your VIN. They'll give you crap for DIYing it, and charge you 1/2 hour- do NOT let them charge you more than that! It's a 5 minute procedure- Mark W.
