HiYa, I'm going to swap in some "real" audio equipment. How do you remove the center dash overlay that surrounds the stereo?
That's the easy part! Start with a few screws on top of the dash, then pry up the top part around the defroster. That'll expose the screws to get the center stack fascia off. The real fun starts with trying to get the stupid security bar off that's bolted to the back of the stock stereo.
Unless you have tiny hands and two wrists per arm, in which case it'll be a piece of cake. Undoing the two bolts next to the defroster outlet to let it move did make it a little easier, but still some bleeding and plenty of four letter words.
I just pulled out the defroster guard and unscrewed 2 screws on the top, and then there were 4 clips that hold that dashboard guard in place, and you can just pry it off
Same here. The defroster guard/vent thing is the long strip where the defrost air comes out. It will just pry off. Start on one end with a screwdriver and gently pry it up. Then just two screws to undo at the top of the center fascia surrounding the stereo, etc. Once the two screws are out, gently pull straight out. It has those 4 clip things that hold it tight. Just pull towards you.
There's "how to" videos on the net if you search for it. Its less work than changing a spare tire. But the first time you do it there's always that "unknown" element. Some people disconnect one of the battery cables first, so they don't accidentally cause an electronic hiccup. Other than that, about the only surprise might be if you accidentally lose sight of a cable back inside the dash somewhere. In that case, it should be simple to remove the door of the glove box and root around with a flashlight. Just don't force anything, keep gently wiggling or prying until you get it. Some of the stuff is just snap-on, snap-off, without screws.
One other hiccup I ran across: the antenna cable is in two pieces. When I pulled the radio out far enough to disconnect the wiring harness, I didn't realize I'd pulled apart the connection behind the glove box. Couldn't figure out why my reception was so poor!
