We've had multiple questions regarding the connection of the factory rear camera to aftermarket navi headunits, particularly the Advent OGM-1 navi, so we decided to document the absolute easiest way to make this connection in the 2011 Silverado equipped with the camera in the tailgate and display in the mirror. This MAY be correct for 2010 & 2012 vehicles as well, but always check first - I can't be responsible if you THINK it's right and make your connections without checking first...

 

The factory wiring for the mirror runs up the left A pillar, and has a nice convenient connection at the bottom edge of the dash just above the left kick panel:

If you peel back the wrap on the harness, you'll expose a white and blue wire in the black plug:

 

gm_camera2.JPG

 

The white wire is camera video positive and the blue wire is camera video negative:

To connect to your navi's rear camera input, just take a six foot RCA cable, cut off one end and strip the insulation exposing the shield and center conductor. The shield will connect to the blue wire, the center conductor will connect to the white wire. We suggest soldering these for the best and most reliable connection, but 3M T-Taps (shown) will work fine too. Stay away from the cheesy kind of wire taps that have the flap that folds over and locks the connection. We use 3M style T-Taps (model 351 if anyone's interested), and don't have any issues as long as you use the right gauge. If you don't use these, either solder your connections (preferred) or strip the factory wire and connect bare wire to bare wire and tape it up.

 

ADVENT OGM-1 NOTES: Currently, since the backup camera screen on the deck comes on as soon as the input senses video, when the vehicle goes into reverse, the camera input will light up and stay on as long as the camera stays on. This may be up to 15 seconds AFTER the vehicle is taken out of reverse. If you want more control over this process, you can either rewire the rear camera's power source or wait until the next firmware update comes out (soon I'm told, and it's DEFINITELY the preferred method). If you want to rewire the camera power source, here's the schematic for the camera circuit - use at your own risk:

Good luck!

I wanted to add a couple photos illustrating the quality that you can expect out of the factory camera on the NBS GM trucks when you wire them to the Advent navi (or any other navi or A/V deck for that matter) by showing closeup shots of how the factory tailgate camera looks on both the factory mirror display and the Advent navi and compared to an aftermarket camera that costs a fraction of the factory's price.

 

Although the factory camera is passable when viewed on the mirror, it looks like ass when you view it on any high resolution panel. It's kind of surprising that GM could actually source a camera with such a low quality image, but if you only have to show it on a 3.5" screen, I guess you don't have to worry too much about image quality.

 

However, when you wire this camera to the Advent, the flaws in image quality immediately become apparent: the overall resolution is pretty terrible and color fidelity is terrible as well. The resolution is so poor that it almost makes it look out of focus.

 

Does it show obstacles? Of course, but depending on what you're counting on the camera display to show you in fine detail, you may not be able to see it well because it will be so fuzzy.

 

Bottom line is that if I had the factory camera already installed, it's highly doubtful I would pull it out for an aftermarket camera. BUT, if I was buying a new truck and had the ability to delete the rear camera in favor of an aftermarket unit, I'd do it in a heartbeat...

 

Here are a few photos showing what you can expect in each scenario - factory mirror display, factory camera wired to an Advent, and aftermarket camera wired to an Advent:

 

A closeup of the factory camera displayed on the factory mirror:

Here's the same camera displayed on the Advent rear camera screen:

Here's one of our aftermarket cameras installed (still taken from HD video):

Walt, can you diable the warning bar at the bottom of the screen? It seems to block the hitch??

 

 

We're talking to Advent about it (in fact, just sent an email today reiterating our preference!) - it's definitely on the wishlist for future firmware updates...

Cool.

 

How easy would it be for me to add a nicer camera in the factory location for the ogm1 that i have coming, and then make the stock cam a second to mount on the back of my salter? That one would go in the mirror and be removed in spring......

The aftermarket camera is definitely better and can be bolted in and wired to the OGM-1 in a half hour. With the current "10-28-11" firmware on the OGM-1, the camera only needs an accessory power and ground connection (do yourself a favor and extend the the power and ground leads for the camera into the cab and connect at the junction block to the left of the brake pedal (fourth port down on the left - ACC power is bottom left, pin 8 - ground is upper right pin #1 in this port). The video output on the aftermarket camera is standard RCA, which plugs into the Advent.

 

You'll have to fabricate a harness for the factory camera for the salter by cutting the harness on the CAMERA side of the weatherproof plug under the truck, then extending all four wires that go to the factory camera as long as they need to be. You'll then be able to unplug the camera when you're not using it.

 

Depending on your truck, you can use these schematics to verify your wires:

Sorry to dig up an old thread but can any one tell me what the other three wires in this set plug are? I have the male end under my dash and am trying to hook up a backup camera and rear view mirror. I have looked at the upfitter guide but can't seem to figure it out. The truck is a 2011 with the YE9 package. Thanks in advance for any help.

just traded my 11 for a 12 with factory mirror backup cam. I'm just going to tap into the factory mirror for my OGM1. Is there any way to take over the camera while in forward motion in the OGM1? I would like to be able to watch my boat from the camera...

Everyone refers to the factory rearview camera in the mirror.

Can someone verify if the wiring is the same for the factory camera that is in the factory navi unit.

I replaced the factory unit with the OGM-1 (much better) but would like to also connect my factory camera into the unit.

 

I have a 2011 GMC pickup.

This is for a 2010 Tahoe, but the Sierra should be the same - this show both navi and mirror wiring:

I know this is a older post but it has already shed some light on my project but also makes me curious about a couple of other things. I have a 2012 Sierra that has the OEM camera and video in the mirror. I am getting my pieces together to install a new head unit. I would to grab the video from my factory camera and run into my new head unit. If I grab the white and blue wire at the kickpanel and run direct to my new head unit, will I lose the video in the rear view mirror? That is what I am hoping..would like to only have video in the new head unit. Also if I run the blue and white to the new head unit what powers up the camera when in reverse? Thanks for any help!

You will not lose video in the mirror if you only tap into those wires, and the video signal is strong enough to support both monitors w/o any problems.

 

If for some reason you wanted to kill the mirror monitor, just cut (or de-pin) the blue wire wire in pin 9:

The most reliable place to grab the reverse trigger is at the junction block (under big black cover to the left of the brake pedal) - it's the dark blue wire in the upper right pin in the upper right plug (gray).

This thread is very helpful but I have one additional question and I've looked everywhere to get a clear answer. I have an 08 Tahoe with factory nav and referse camera. How do I give the oem camera power to turn on while I am driving? Since I have factory nav now it isn't displayed in the rear view mirror so I'm not sure if I can tap into the wire mentioned above.

 

I'm trying to avoid having to run a new wire all the way from the oem camera up to the dash to give it constant power. Any help is greatly appreciated!

      Some Assembly is Required

      By Grumpy Bear · Posted

      Can it still be Assembled I?    Stribeck says that we need a certain amount of viscosity under conditions of load and velocity to prevent two surfaces of a know roughness from tearing each other asunder. And we have marketing trying to tell the masses that those two surfaced require less of that commodity due to more exact limits being placed on the same old clearances. We also know that there are limits to how hard something can before it becomes to brittle to be viable and to smooth to 'wet' the surface and that both of those conditions have been known and met since about the Second World War.    That viscosity value shook out at 10 centistokes at 212 F just under a hundred years ago.  Give this a look: [Anton Parr]     What is advertised is the Kinematic viscosity (mm2/s) or that which has been density adjusted but the value we are after is the dynamic viscosity (mPa.s) or true viscosity. You can see that this number is dependent on density thus base stock and temperature. You can also see that an SAE 30 doesn't reach that value in this example. However an SAE 30 that is at the upper end of the SAE 30 range; 12.5 cSt (mm2/s), might. 12.5 * .83 = 10.375 (mm2/s). If you could find an SAE 30 at the upper end these days.   Then there is the complication of viscosity modifiers or VII or VM, whatever you wish to call them. Polymers added to very thin base oils, perhaps 3 to 6 cP oils, that will meet the SAE *W30 spec at 'tested' shear rates and 100 C/212F  target temperature. So a polymer fortified base that is a fraction of the 10 cP requirement Stribeck insist upon.   This could be all well and good if those polymers didn't have two very problematic 'features'. They shear or loose viscosity both 1.) permanently and 2.) temporality. And they do both omitted in the advertised data with the distinct  purpose of deceiving the consumer of the actual operating state of the fluid. I've shown the example of Warren Oils COSTCO 10.91 cSt 5W30 formuation several times where the 100 C HTHS value is 6.9 cP!! That's the temporary shear down and with and SSI or shear stability index of 9.4 cSt. Note the intentional deception in using mixed units?    After a short while that 9.4 cSt oil has a viscosity corrected dynamic value of 7.8 cP. But as the SSI is still within the range of an SAE *W30 whose lower value is 9.3 cSt.    This allows them to continue to call this SAE 16 weight oil a 30 weight, the cake, and still meet the API requirements for fuel efficiency IMPROVEMENT mandated by the EPA. The eating of the cake. By the time you've worn out your motor doing the responsible thing by adhering to the warranty requirements, (the stick), you get deprived of the carrot, wear control. So sad, to bad.   So what can be done? Do I need actually say? [Anton Parr]       Even this must be monitored if the oil is on the low side and the VII an organic or you opt for a 0W40 with an even lighter base oil and more / higher MW VII. (Note the lower density of the 40 weight versus the SAE 30 mono-weight?)    There is another workaround. Temperature. An SAE *W30 run at a bulk temperature of between 180 and 195 F.    Being the belt and suspenders sort I am I do both. Run it cook and run it heavy.    In Part II I'll work the AW package.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      So, do I go elbow-deep on this thing or list it for sale and play dumb? Seems to "runs good."   I'm about $1200 away from having: -a rebuilt injector ($300) -a new cat ($250) -a new cat back exhaust (OE style) ($300) -a new AC compressor ($200) -AC refrigerant charge ($150)   In theory, this should rectify the obvious detracting issues from its value and operability. Cold AC with a non-squeaking AC pulley both sounds and feels good. An exhaust that isn't cut/hacked in 17 different places and doesn't vibrate on a crossmember would make it sound and feel less janky. A working cat would help the stink, and will save the earth, but *if and only if* the fuel system is working properly, which would also address the intermittent "rich" CEL.   Heard a good one... CEL for "Rich condition" means you haven't spent enough money on the truck lately, and it's letting you know.   Rebuilding the injector would seem to be the most important part. Replacing the cat would be secondary. I don't think mine is plugged or overly restricted, but it might be a little restricted? I have no good way to tell other than seat of the pants feel. I hate the smell.   The current theory is I have a rich idle problem: A bad fuel pressure regulator, or a leaking injector(s) being the highest probabilities. I already replaced the FPR but that doesn't mean its replacement isn't also bad. It was a new part from Dorman, but the packaging looked like it had been sitting on a shelf for 20 years.   This is the (single) upstream O2 sensor shown at idle. I'm getting a lot of "rich" it seems. Sometimes it stays high like that and doesn't drop down. That makes me think it's processing injector leaks or a partially stuck open injector.     Other times it looks like this. Nice oscillations between rich and lean, which is what I think it should be. Under load and at speed, the oscillations are nice and tight and uniform looking, high and low.     Fuel trims suggest the PCM is compensating pretty hard at idle to pull fuel out. But it's not enough to trip a CEL. Something about slowing to a stop: brake vaccum booster, EGR, or the EVAP purge is delayed, or there's pooled fuel in the intake again that's draining into a cylinder is enough to set the CEL. Of course, in two days of driving, it hasn't set. I was hoping to actually look at the freeze-frame data when it sets. IAT is high because it's idling on an 83 degree day here.

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.
