You can buy special tools, but a flat tipped screwdriver with a piece of electric tape is what I've used for 17 years with success

Don't pry around the HU. Pry around the top of the cover that near the top of the vent(see the orange arrow in the picture). |

I did not, but do now! Thanks for that, now I have an idea of what to do and look for. I got the same camera and it came today...install begins tomorrow. I'm a little different though having the NAV HU, according to SVXDC, I need to find a power source for the camera that has power in accessory mode on the ignition switch, so reverse lights will not work for me.

Seems like as long as camera can generate video signal when you are in reverse, that should be good enough already. Why would you need accessory mode power for the camera all the time. I would suggest that you try out some hook up options first at the HU to make sure camera image shows up at the HU before any kind of wire routing/camera mounting work. Good luck. |

But of course, even as he, (and you) suggested, I will be testing it before I run all the wires and mount the camera. Also, maybe you can answer this....I was looking at mine today and I have a small red wire on the camera harness that extends next to the yellow RCA plug...does yours have that and if so, what is it for? |

I had a heck of a time finding 12v with accessory on, but then it dawned on me, I have the oem subwoofer installed and sure enough, there was a red and black wire waiting for me to tap into. So, I again tested it with the camera and it worked like a champ. I ran the video wire all the way up and plugged it into the back of the new video cable in the HU, and now, all I get is the parking lines, and the check surroundings warning, but no video. I have tried everything and triple checked all my connections, but I have no idea what happened! My only guess is the camera itself is bad. |

Very sorry to hear that the camera could have died. If you have a TV that you can hook it up to, you might want to test it to see if the camera has died. If you read my posts, you'll know that my first camera was bad. I had some "cold boot" problems. I had to exchange it to get it working. I wouldn't be too surprised if your has died. I did noticed that the camera does get warm as you use it. I am concerned that having it power up all the time might have "stressed it" too much and it burnt out. Since my only turns on for seconds at a time, only when I'm in reverse, I hope it won't burn out too fast. |

You really need to find +12V Accessory. Worst case, extend the camera's power wire up to the HU, and tap in there. |

Some cameras have one or two short loops of wire near the camera. The instructions will explain that they enable/disable some options (by cutting the loop). One controls whether to display or not display parking guide lines. Another determines whether the video image is normal or mirrored. Same cameras don't have one or both of those. Quote:
If you have a choice between using the grid lines built into the camera vs. the grid lines from the HU, it's better to use the HU's, since you can use the setup menus to adjust their position. |

Well now, I'm a little confused....if it's looking for a video signal, and NOT 12V, then it shouldn't matter if I tap into the reverse lights or not, so long as the video cable from the camera is connected to the HU, correct? Not trying to sound argumentative, so I apologize if it comes accross that way, just trying to understand. Also, I don't believe you're correct on how the sub is powered, at least not 100%. I know for a fact that if I turn the key to accessory, even if the radio is OFF, the green light on the "amp" turns on, and no matter how long music isn't playing, it stays lit. Only when I turn the key off, does that green light go out. |

The HU checks for the camera by looking for the video signal The HU only uses two pins on the 16-pin harness for the camera -- for video signal and shield/ground. A camera will only send a video signal while it has power. So if you power the camera from the reverse lights, but the reverse lights are off while the HU boots, the HU won't see a video signal, so it will decide that there is no camera plugged in, and disable that feature. To put it another way, the camera must receive +12V power while the HU boots, so that the camera is already sending its video signal to the HU at the moment when the HU checks. |

I had connected the extra red wire to a 12V source, when I did that, the camera stayed on even when it was in drive. To be honest, I don't remember if it stayed on when it park, but it wasn't acting right, so I disconnected it.
Now that I am thinking of it, perhaps if I ground the wire to the chassis, it will disable the grid lines. Hmm, might have to play with it to see! |

Ok,I got the new camera and did a quick test...old one was definitely fried. So, I tested the subwoofer wires I was using for power and SVXdc, you were correct, they receive 12V all the time, even with key off. So, if I hook up here, my camera will constantly be powered, correct? Is it really a big deal? I mean, if I power it to have 12V when the key is on or accessory, it will still be constantly powered when the key is on, even when not in reverse, correct?
Edit: If anybody has any suggestions (aside from running wires all the way to the radio) to find a 12v key on source, I would be willing to entertain that! Last edited by jsteg; 09-07-2012 at 04:50 PM. |

If you are going to run the AV wires to the HU anyway, why not just run the power wires as well?

They're not that long, and I didn't want to splice new wires and run 2 additional wires all the way up there. Plus, I don't know which wire to hook it to up there either.

I like the idea of the camera I am going to do this myself.

Wagons may have a 12V accessory outlet near the hatch. If yours doesn't have a wire with that near the back, you might as well buy some extra wire and run that alongside the camera's video cable all the way to the HU. You can tie into the wire for the front 12V accessory outlet, or tap the lead for the HU's +12V Accessory power. Posi-Taps are a great way to do that. |
