2011 Forester XT, 4200NEX

Post by wighty » Sat Dec 16, 2017 8:13 pm

Hi guys,

First time replacing my headunit with an aftermarket since about 13 years ago :P

I have:
2011 Subaru Forester XT Touring (Bluetooth, no navigation), auto trans
Pioneer 4200NEX (4201 packaging, not installing the camera)
Maestro RR
SU1 harness

Followed page 4 on the Rr installation guide for wiring instructions.

3 questions:
1) It seems like everything is working EXCEPT for the OEM backup camera. I switched the 4200NEX setting to Rear view camera on, so when I put it in reverse it looks like it is switching to the input but it is a black screen (with some of the white text warning at top), still on "battery" setting. Was there anything additionally I was supposed to do beyond the wiring guide to give the rear view camera power? The only thing I wasn't sure of on the installation wiring guide was the Purple/white (NC) which I took to mean No Connection, so I didn't do anything with it.

2) Does the maestro hook in to the OEM microphone from the bluetooth setup? Or am I going to have to run the ugly external mic that came with the 4200NEX?

3) Looks like there was only one cable from the OEM headunit I didn't use other than the SiriusXM radio, the one circled on the left in red... what is it? https://imgur.com/a/zYTvq

1) If the camera screen is coming up when you go into reverse, the RR is doing its job of switching the screen for you. The T-harness should power the camera on without any additional wiring. What did you do with the yellow RCA plug? It should be connected into the brown RCA port on the Pioneer.

2) The OEM microphone cannot be retained, so you must use the Pioneer microphone.

3) That looks like an OEM USB, if your vehicle is equipped with one.

1) T-harness yellow RCA plug is going into the brown RCA on the left side of the Pioneer. I unplugged and reconnected all of the plugs to verify the connections are good. C harness has both the blue and yellow plugs, and then the RCA going into the headunit.

2) Bummer

3) Yeah it has an OEM USB port.

One last thing you can check is to see if the camera is getting power on the blue 2-pin plug of the SU1 harness.

The blue 2 pin you are referring to, is that the one connected to the "C" harness that has the yellow RCA video input for the backup camera? If so, it looks like that was reading +5V both in park and in reverse.

That should give power to the camera any time the ignition is on, approximately 5v

Sometimes the camera output doesn't have enough current to turn on certain camera modules. Subaru had a few different camera manufacturers- clarion and fuji heavy industries. The fuji cameras tend to work fine with the harness configured as is, but the clarion camera requires more current. To fix this:

De-pin or cut the blue/yellow wire from the green plug on the maestro. Populate wires in pins 2 and 4 on the RR's black 18-pin harness, tie them together, and hook them to the blue/yellow to power the camera. To do this, you can use the extra 18 pin harness that came in the RR box, and de-pin some wires from that plug. The image shown below is wire side, FYI.

"hook them to the blue/yellow to power the camera"

I just want to confirm you referring to the blue with yellow stripe coming off the blue plug from the C harness?

Correct, the one in the "C" connector

So I tried this, and it didn't work. I initially screwed up and depinned the blue/white from the green plug on the maestro (at an angle it definitely has a slight tint!) but fixed it and still no go. I tried testing the voltage at the blue/yellow on the C harness and I did not get anything.

You didn't populate wires in pins 2 and 4. It looks like you did pin 2 and 18. That definitely wouldn't give you the desired result.

Well I was clearly tired when trying to do this originally. However, I populated 2 and 4 and it still didn't work :-\

You probably damaged the camera power output on the RR when you hooked to pin 18- that's a ground. At this point, the maestro would need to be swapped for that output to work. You can hook the camera's turn-on wire to 12 volts.

Not at all! There is a 1 year warranty- you can either exchange the RR through the dealer where you purchased it and get a replacement, or wire the camera up to 12 volts. I'm just making sure you know all your options.
