DIY: USA-SPEC iPod Interface EX/SC
I installed this last night, and during the install, I took a few pictures.
I will post the pictures and go over my install with you. It took me
about 1 hour and 15 minutes. That being said, while I was doing this,
I also changed out my cabin filters, and took pictures. If I do another
one in the same manner, I could probably do it in 30 - 45 minutes.
I purchased the PA15-HON2 from HandA. It is on special this month.
The kit is very simple and you just need to decide where you want
your iPod to sit. I chose the glove box for two reasons. It was
simple, and with the amount of control the interface gives, no reason
to see it all the time. I am not sure if the cable will reach the
center console. I'm guessing if you do it right, it will. This is for the
EX and SC models only. The LX uses a different USA-SPEC interface
and has a completely different stereo. OK, onto the good stuff!!!!
Disconnect your car battery!!! I dont want to hear about it if you dont.
You need to remove the U shaped face plate from around the stock HU.
I used two pieces of blue tape, you can use masking tape, and put them
under the face plate (pic 1). I pulled lightly, and the face plate came right off.
In the instructions, they tell you to use a screwdriver with a cloth around
it, dont do it!! After the face plate is off, just four screws to take off (pic 2).
Unplug all the connectors on the back of the stereo, and remove it.
You will need to remove the two bump stops from the glove box, so it
will fold all the way down. I put the interface behind the glove box, and
ran the iPod wire into the glove box. Picture 3 shows the glove box folded
down to the floor and what is behind it before install.
Here is a pic from ramblerdan on the glove box:
NOTE: Good time to change your cabin filters at this point!! I have only
10K miles on my E, and they looked nasty!!
You will need to run two wires from behind the OEM HU to behind the glove
box. The HU to interface wire and an orange wire from one of the other
wire bundles. The first cable is black and has a large 8 pin DIN connector
on it. The DIN connector will need to go behind the glove box. I put one hand
in the opening of the OEM HU, and one hand in the glove box opening and to
the left toward the center console. I taped the orange wire from the other
wiring harness to the black wire, so they would both go at the same time.
I wiggled the wire down from the HU opening and caught it with my other
hand. I ran the wire OVER the metal bracket that frames out the glove box.
You can see where the wires ended up in picture 4, top left corner.
You will now need to connect the OEM wiring harness to the USA-SPEC
wiring harness. Picture 5 will show what it looks like when you are finished.
The instructions say that the OEM wiring harness is a 14 pin male, but it is
a 14 pin FEMALE connector, and it is white. All the other connectors, the
black one, the blue one, the green one, and the grey one all go back to the
OEM HU as they were before. The OEM white 14 pin female connector goes
to the CAS-HXM cable. This is the harness that has the orange wire that I
spoke of earlier. This harness also has a blue wire that will NOT be used. I
put a spot of black tape on the end of the blue cable just in case. The
CAS-HXM 14 pin female connector then goes into the 14 pin male connector
of the CAS-H2Y cable. This is the black cable with the large DIN plug on it
that I spoke of earlier. The 14 pin female connector of the CAS-H2Y cable
will connect to the OEM HU.
Set the dip switches on your USA-SPEC interface. Picture 6 will show how
I set up mine. I set mine up for FOLDER mode.
