Some things to note about the disassembly of the dash.
1. Be VERY careful. I used the 2008 service manual .pdfs I found on this forum to walk through the process. Everything was the same as the 2008 on mine so I'm hoping that means this head unit install will go OK.
2. The plastic side trim pieces that run on either side of the center console are kind of stubborn. Mine are shiny black but these could be wood grain or some other color on other vehicles. Anyway, there is no obvious starting point. I started at the bottom with a small screwdriver and gently pryed enough to get my fingers under the bottom of the trim pieces to start pulling outward. The vinyl dash material is not very tough so it will mar easily with pry marks if you apply too much pressure. Anyway, once you get the bottom of the strip out enough to get your fingers under it, start pulling it out from the dash (straight back toward the center of the vehicle. Work your way up the strips with your hands to gently pull them free. They are stubborn and they WILL sound like they are breaking when they come off. But they do come off.
3. The little cubby box next to the power outlet is next. There is a rubber mat that needs to come out first. If you ever so gently pry up on the rubber along the edge nearest the shifter you will see an indentation in the plastic under the rubber. The notch is about 1/4 of the way from the driver's side (it's not centered). DO NOT PRY UP ON THE RUBBER PART. That is glued onto a plastic shelf and your goal here is to take the whole shelf out with the rubber intact. Get the screwdriver (cover it with electrical tape first or risk marring your trim pieces) and pry upward on the edge of the storage cubby "floor". It is a little stubborn but it will come out. Once you get that back edge pryed up across it's length, you should be able to remove it by grabbing it and pulling outward (toward the shifter). You might have to tilt it upward a little first.
4. Now, you have to remove the trim piece that goes around the shifter. The entire piece come straight up. I started with the front edge (which I just exposed by removing the storage cubby bottom) and worked it upward and back. It came free and then the whole piece comes up and over the shifter. The light bulb socket is there so if you plan to keep this part safely out of the way, depress the small plastic tabs on either side of the light socket and release it so you can set the shifter trim piece aside where it will be safe.
5. With the shifter trim out, you now expose a screw in the lower right corner of the console bottom (the storage cubby and power outlet section). Remove this screw and you can release the bottom of this piece from it's clips by grabbing under the bottome edge with your finger tips and pulling upward and back toward you. Once that releases, the top of that section unhooks from the upper console section. Keep working it gently and it should release from it's top hooks easily. The power outlet will need to be unplugged to set this section aside where it will be safe. NOTE: You may have to turn the ignition on and shift out of Park temporarily to completely get this piece out.
6. There are two screws on either side of the main console (about the same height as the air vents). If you haven't removed these yet, remove them now. Now the ENTIRE center console trim, all the way up and around the top of the dash to the center speaker comes off in one piece. Start at the bottom. pull straight back on either side with your fingers hooked under the bottom edge. Once it starts to release, work your way up either side pulling STRAIGHT BACK. Don't lift up as you go higher. All of the clips are made to release pulling straight back to the center of the vehicle. It should come loose pretty easily. Unplug the 3 connectors at the bottom for the HVAC controls and the connector at the hazard switch and the entire center console trim piece can be set aside in one piece for safe keeping.
7. From here, it's pretty easy. 4 screws release the head unit. Mine has a 10mm bolt attached to a metal tongue on the lower left that had to be removed as well that was not in the instructions for the 2008. Not sure if that is only a 2012 thing or they just missed it in the instructions. Once the bolt and the 4 screws are removed, the HU comes straight out. The wiring didn't let it come out very far however so getting them released was a little awkward. I used a small screwdiver to help press on the release and they all came out fairly easily. My HU had 4 connectors. Not sure what they all are yet, until I get the wiring harness. The grey one with the large black cable is the antenna. That's when I noticed it wasn't standard and I had to order an adaptor.
Anyway, that's where I'm at so far. there looks to be plenty of room in the dash for anything needed that goes with your head unit. My Kenwood has an XM Radio add-on that I'll be using.
One thing I didn't notice was there was no obvious antenna hook up in the HU for the Sirius receiver. I suspect that is likely a separate unit and the antenna lead plugs into that. I'm hoping that is there in the area so I can perhaps use that lead to plug into my XM unit (so I can use the OEM SAT radio antenna). Anyone know about the OEM Sirius set up in these?
That's it for now. Will keep you all posted. If all my stuff get's here this week, I'm hoping to get this done this weekend. Again, I've learned not to get ahead of myself so not counting on it - just hoping
Later.
