I finished wiring a iDataLink Maestro RR to a Pioneer AVH-4200NEX for my 2016 Scion iM. Everything but the backup camera works. I already knew this was gonna happen because it was mentioned on the forum that I would need an AX-TOYCAM3 harness to retain my factory camera.
I purchased this one on ebay:
I have the harness now but I have no idea how to wire it. It comes with a stripped yellow and black wire, and a male and female rca plug.
How do I integrate this harness with my idatalink maestro/4200NEX setup?
What do I do about the reverse gear signal, or is it already included in the camera harness?
I installed the iDataLink Maestro RR and Pioneer AVIC-8200NEX in my 2018 Toyota iM... What a pain in the butt! The following video was helpful for the entire installation.
The guys in the video are installing an Alpine into a Toyota 86, but it is pretty much the same (at least as far as the stereo wiring goes). Fast-forward to around 18:20... that is where they talk about how the Maestro does not pin into the back-up camera... they show (tell) you how to fix it... It worked for me and it wasn't that bad.
You do not have to worry about the camera voltage... the video shows you how to get the reverse signal to activate the head unit.
I remember putting in my Pioneer head unit ,something like six harnesses to install it.I used the rear stock camera and mounted the Pioneer camera in the upper front grill . I installed one of Pioneer brick looking amps behind the dash to power the four doors and a mono Pioneer Amp placed under my seat to run my sub....2 years later no issues ...Plus I did Dynamat my doors big difference and did Boston Acoustic Pro 6.5 sets in my doors ,Boston is not making car audio anymore..these were from my older car ......
I have watched this video so many times and just don't understand what he means on the camera. I have a 2018 IM as well with the pioneer DMH 1500nex. I know I need the cam wire adapter but what is he talking about the reverse function. Honestly, any help will be a lifesaver. The main issue is I just need to know how to get the two white/orange cables together. How do I pin into the harness as he states?
