I'm done installing my Pioneer AVH-W4400NEX Carpplay/Android auto stereo in my 2010 Boxster (987 Gen 2). I'll explain the whole process here. I bought the stereo, adapter, and faceplate on Crutchfield since they have support and gave me some advice. My Boxster doesn't have the Bose system which makes the installation much more painful because you (may) have to replace the speakers. Fortunately I didn't have to do that, but I did have to run a power wire to make sure the amplifier under the passenger seat is powered up (I'll discuss later).
To get through this, I consulted a lot of sources. Some of them are
Article on where to find the amplifier power wire and switched power wire
PDF with a lot of excellent wiring information
Pelican Parts article on installing stereo (not exactly right color wires for 987 Gen 2)
I bought the factory service manuals for
emanualsonline which are helpful but basically it is a web site made into a PDF so it is hard to find anything
How do remove the center console
First of all, you need to install your backup camera which I did by connecting it to the license plate. I ran the wire through the hole in the back bumper and I removed the rear right taillight and ran the wire through the hole there. I used a bent clothes hanger to get the wire through. Then I threaded it through the rear trunk into where the soft top is. To run it through to the door jamb, I put the soft top in the service position (half way up) and threaded it. While you have to rear tail light out, you'll need to run another wire for the reverse sensor wire (this is the signal that turns on the backup camera when you are in reverse). I tapped into the blue/black wire running to the tail light and ran it in addition to my camera wire. This wire is also connected to the control unit under the drivers seat but that was too hard to get to and I already had to disassemble everything so I found it easier to run this from here. Thread the wires down the door jamb, under the door sill and to the front.
