Hi all - first post here. I wanted to see if anyone could provide a definitive answer regarding interfacing the OEM backup camera to a Pioneer AVIC-8100NEX in dash nav, or any other nav HU for that fact. I've seen some posts say you can just alter an RCA video cable and interface that way, and others say you need something akin to a Beat-Sonic BC6+BC1 interface adapter. Part of the discussions I've seen also say there's a need to step-down the +12V signal to 6V in order to properly capture the signal.
So, with that said - does anyone have a definitive answer on this? What has worked? I apologize if the answer is buried somewhere in these forums, but if so, I'd appreciate some guidance one way or the other.

Thanks in advance for any responses and help.

Have a great day!

I just used regular rca spliced into the wires in back of mini info screen for my nex5000 works great. Don't really need an adapter.

EthanSienna:
You've never had a problem with your wiring method? Did you simply wire the reverse signal out of your nex5000 to mini screen reverse signal, and then the RCA wires to the mini screen video+ and video-? If this is not correct, can you divulge?
Thanks again...

Has anyone else attempted the RCA cable interface and not been able to make it work?

Some it really depends on the aftermarket unit I guess. Or trim level maybe? Can't seem to make my oem usb plug work with pioneer(some says it works with xle and upper?)

Here's the article that been referred to in other posts. It shows how its author replaced his stock radio with an aftermarket unit and how he connected the stock backup camera to it. For whatever reason, however, his method for backup camera connection didn't work for me in my 2013 LE with my Pioneer AVIC-8000NEX.

I used this for instruction for backup camera wire http://m.youtube.com/watch?v=YJKP2fEHl9E. At first it didn't work for because I plug into display out on nex unit. The Nex Manual r confusing to say the least. So check ur wiring it should work. I know how much it bugs u camper

What method DID work for you? Do you remember? I've seen most of the references people point to like the link above (alexapps), but people still report failures while some say it works....I'm wondering if it just comes down to loose taps, incorrect wiring, or bad solder (shorts too?). The whole 12V vs. 6V argument doesn't seem resolved in most forums either....but as EthanSienna said, different trim packages may present slight differences in wiring, combined with the various head units people have installed.

I haven't attempted any other method yet. The summer heat has made sitting in a parked car for hours not very attractive. When the weather cools a bit, I'll try again.

Thanks for all the responses. One last questions regarding the in-dash nav install: where is the easiest location to tap into the vehicle speed sensor wire?

My in-dash nav has a speed sensor input, and I need to tap into the vehicle speed sensor wire. Would be great if this wire was directly behind the stereo somewhere...
