It is pretty easy if you have a few tools and know how to use them.

1-You need to pry off the trim bezel. There are just snaps holding it on, but be careful you do not pull too hard or scratch it. Use a plastic stick or small srewdriver covered with tape.

2-There will be 4 bolts at each corner of the radio to remove.

3-Pull out the radio and and remove all the connectors and the AM/FM antenna plug.

4-Reconnect your new radio and repeat steps 2 and 1.

I did this same upgrade on my 2005 Jeep Grand Cherokee and it worked without the need for a theft code.

To run any wire through the firewall, find a spot that is both reachable and unobstructed on both sides of the wall. I generally use a very short bit so after penetrating, it does not accidentally plunge into other wiring or components, or I use a collar over the bit (a small piece of tubing, leaving only 1/4" of bit exposed) I sometimes also "cheat" by poking a hole in the rubber boot where the steering column goes through.
Whenever passing a wire through sheet metal you must install a grommet. (if none are available, you can make one by using a piece of rubber tubing or the cut off end of an old tire valve.)
When tapping power from the battery, you will need to use a relay and switch attached to the "accessory on" side of the ignition switch, to prevent whatever you are installing from remaining on after the vehicle has been turned off. Use fuses in all new power sources as well to protect the vehicle and your new install from damage.
In creating a new circuit, you have the opportunity to use shielded wire, which will prevent stray electrical "noise" in your set" not a bad idea to do that.
good luck
