This is my first post here, but I thought I'd put in my two cents for the novices installing stereos. I've never installed a stereo before, but I consider myself handy and have a few tools. Basic wrenches, screw drivers, and a wire stripper.

I have the most base model 2009 JK unlimited with the stock single CD player, RES stereo. Non infinity system, and I have the iPhone 3GS.

I ordered the Pioneer FH-800BT, which is the same as the FH-8000BT, except it was $20 more and had a year longer warranty from crutchfield. I got this model because of availability, and if ordering from Crutchfield, you get the CR2 CHY2 (EDIT, I MEAN CR2-CHR4) PAC harness for half off, as well as the correct dash kit and antenna wire too. I also picked up the IPOD mount from Quadratec.

The harness works perfectly, splice colored wires from the aftermarket radio harness (came with the stereo) to matched ones from the PAC harness. The PAC aftermarket plug fits into the factory stereo plug, no splicing wires that are connected to the Jeep itself...I was worried about was there were 3 wires left unconnected from the PAC harness, but after reading through the wiring diagram from the PAC system, I realized that they were not needed, as I did not have an existing or aftermarket steering wheel control (SWC, the white green wire), the stereo I got did not have a reverse input (green), or VSS (vehicle speed sensor I think) Purple/white.

The toughest part was the metal frame/plate from the back of the stereo cavity. Some other people have used a saw or dremmel to get the top portion of it out. I opted to take it all out, there are 2 bolts in the bottom that were a bitch to get out, because I didn't the correct size fixed wrench, just a socket wrench, so it was a tight fit. Also, once those bolts were off, I cut 2 plastic clips that anchored a bundle of wires to it. Finally, it took some brute force bending the plate and getting it into the perfect position to take it out, but it came out...at the cost of some scratched hands, so use some gloves or a towel. The stereo fits snugly and is propped up just fine, so I don't see why to leave it in there and just saw the top off, but that's me.

Other than that, everything else went in easily. The antenna took some force to get cooked up. I originally packed all of the cords behind the stereo, but decided to move the PAC box and most of the wires to the right in the back where there was some room to allow the radio to fit better and I ran the USB extension and microphone wire to sit on top of the stereo, and just rest under the top dash piece, the one that pops off first without screws. I did this so I could play around with the placement of the microphone and ipod wire (which came with a long extension) without taking everthing down again.

The iPhone 3GS works perfectly. All controls are available through the stereo including access to all playlists and functions. If you have a GPS program (I have Navteq) that has voice directions, you can simultaneously control the iphone music through the stereo, charge the phone, see the map, and get voice directions through the stereo system. Bluetooth pairs easily once you find the correct menu, and my phonebook downloaded in 2 minutes. Interestingly I also found out that I could stream music through bluetooth, which sounded fine, but I like plugging in my phone to charge it and control it through the stero any ways, especially since my GPS program really drains the battery. I have not made a call yet, but everything pairs up quickly once you step into the car.

The system sounds great. Sound clarity as well as intensity are immensly improved with just the headunit and no aftermarket amp that I am holding off on speaker upgrades. Unless I can find a great deal, I'll likely hold off for a bit. I enjoy music and listen to a wide range, but am no audiophile.

Ok, goodluck.
