Default Pioneer AVIC- Z140BH install w/ backup camera/ xm on 2007 sti

yesterday i installed the new Pioneer AVIC Z140BH Nav unit in my 2007 sti. I thought it would be helpful to share my install tips.
Speed Sensor- the green connector connected to the speedometer, and the spliced wire is indeed Green with a black stripe.



Reverse Signal - Instead of having to feed a wire all the way back into the reverse light, i took off the right kick panel and spliced into the Brown/ yellow stripe wire running from the back of the vehicle.



Handbrake bypass option- There are a few videos on youtube showing the procedure to bypass the handbrake switch. the RCA cable wiring harness has a MUTE wire thats yellow/black stripe, all you do is move it one pin above its original connection and connect it with the handbrake wire located on the other wiring harness then you ground it to chassis( what i did is splice it into my ground wire on the harness, which when connected leads to ground in the original subaru wiring harness. which in turn grounds to the radio bracket with a connector. works very well


I installed my XM radio receiver box right below my clock/airbag on/of sensor trim
it seems to fit pretty well and i used double sided tape to hold it in place. it has a ground wire running of off it(i grounded all my wires to the bolt on the driver side under the carpet, the bolt holds the dead pedal in place.


Rear View Camera- I wired the camera from the trunk through the back seat and ran under the passenger carpet. it has 3 wires; brown RCA that runs to the nav unit, and a ground and power wire. the power wire had a 1 amp fuse, so i replaced that with a "add a fuse" wire (with 2 amp fuse) and connected it to #5 fuse behind the coin holder. i installed it this way so it has power when ignition is turned on, so there isn't any signal issues with the brown/yellow reverse signal wire.

Everything was ordered through crutchfield and i am very pleased. I also received the wiring harness that connects the nav unit harness to the original subaru harness and it in fact works. surprisingly the colors on the wires match up with the nav unit wires.


Heres the finished product.





All of the information i used to help me with this install did come from nasioc forums. great sources here

Thanks
Adam

Hey, I just bought a rear camera for my p8400bh, and I'm having a trouble getting pictures on the screen. I connected the rca(yellow cable) to the back of the headunit, and connected the red(power) wire to left reverse light wire, and the black(ground) wire to the left reverse black wire. The picture didn't show up when I put the gear in reverse, did I do something wrong? any help would be greatly appreciated

Try turning on your parking lights and then put it in reverse, or your lights in general. Depending on where you spliced it specifically can make a difference. I spliced my camera into the kick panel area because i wanted to be able to have picture from the camera in different ways. if there was a fuse connected to the camera wiring , see if it maybe has blown

The Z140 should fit. The only issue might be the depth. At least for the size of the OEM radio and dash opening, STI is same as WRX.

1993-2007 models can take a standard double-DIN size HU. No dash kit needed -- you'll re-use your factory metal radio brackets, and the factory bezel/fascia has the correct-sized opening.

See this thread for more tips:
Stock head unit information -- pin-outs, subwoofer, aux inputs, and more
BTW, on recent Pioneer AVICs (Z130, X930, Z140, X940), if you do the bypass hack, you do not need to ground the parking brake lead. Just insulate the end of the HU's brake wire. Also, I have wires with the proper pins to fit the AVIC's RCA harness (so you won't have to extract the mute pin/wire to transplant that). E-mail me for details (see my profile -- click on my username).
