Oem Navigation With Factory Installed Rearview Mirror Camera

I just bought a 2011 LTZ Silverado with the camera system in the rearview mirror. I was looking for a truck with the navigation system but there wasn't one that I like within 700 miles so the dealer said I could upgrade the stereo to the Nav system and the camera would probably end up showing the image in both the rearview mirror AND the nav system. So I paid the bundle of $$ for the upgrade and they installed it today. About 30 mins before they were done they told me they probably couldn't get the camera system to work in the nav system "but it's ok because the mirror camera still works". I told them that I'm not paying that much $$ to only get a subpar GPS system. They finally relented and are looking into a solution. They told me that the GM website says the conversion will work but when the tech called to get some support they said it won't work. I'm having a very hard time understanding how a factory installed camera system can't work with an OEM upgrade? Wouldn't it be the same wiring and connections if it came from the factory with the nav system as it does with the rearview mirror system? Couldn't they just unplug it from the mirror and plug it into the nav system? When I put it in reverse the mirror camera work and the new nav system is black and says "check your surroundings" and I made sure the everything was turned on. Has anybody else come across this issue? Thanks for your input!!

Sounds like only the video input itself is not being fed to the navigation system. Like the need to split the video signal or just route it solely to the navi. Odd but when I think of how GM stock radio units are and how they don't switch out easy at all, it makes sense that the tech can't figre it out.

The truck is harnessed for the rear mirror video. You'll have to intercept the video feed and reroute it to the back of the Navi unit.

I say make the dealership take it to a custom audio place that knows what they are doing. It should be an easy splice to your mirror and the nav unit.

This is what the guy at justanswer.com told me.....I think that's a huge mistake that GM made. Why would they make it impossible to upgrade with their OEM products installed by their technicians? And why wouldn't the 5 people at the dealership that I have been dealing with tell me this stuff?

 

sorry, If the 2011 came with "just" the Mirror type, it will NOT work with the added NAV Unit, as it requires a different Harness for the NAV Unit

I have done a number of these & GM does not have nor a adapter Harness for the needed swap as yet

 

The problem is not only the harness but the "programming" of the Camera into the NAV Unit

All components go thru the BCM (body control module). If the BCM that came with your truck does not support the NAV type Camera, then it can't be done

 

This is not unusual, as GM is trying very hard to make any changes almost impossible without Factory complete systems (harness, modules, components, programming & BCM)

To my knowledge the camera system on the trucks use two wires for video and get the power and reverse signal from the bcm. You should be able to run the video feed from the bcm to the HU for the image I believe. Your HU is set up to take the signal if you see (Check Surroundings) warning. Also you can turn that screen off from the menu if you like.

 

Agreed It's damn shame that after dropping that kind of cash for an upgrade GM can't make it to where all its capabilties will function.

I don't think that when they are building the truck they do it with the intention of people upgrading things. They try to make them work as best as they possibly can, then crafty people work backwards to figure out how to upgrade their vehicles as cheap as they can. Sometimes it works, sometimes it doesn't. That's why the dealership probably didn't tell you. They didn't know, and it's not like there is a place they can go to find out.

      Missing thrust bearing? And oil selection

      Lake Speed is drumming up business for his company just by being in the spot-light so he has a vested interest in stoking the 0W-20 fire.  IMO

      I knew when I bought my truck that it had off road hill decent or craw control or whatever they call it and rolled my eyes at that but it gets throw on with other options my truck has, I just never had a heads up if the highway speed regular cruise setting had anything to do with the brakes and that took me by surprise. If you've ever been to the top of Pikes Peak and watched those ahead of you on the way down with their brake lights on constantly, one can guess they are probably not gearing down or not enough anyway if their vehicle will allow and a good reason their is a brake check spot part way down where they use an infra red heat gun to check how hot ones brakes are front and rear.    Your right that once one gets out of the front range by Denver and I've not been on that stretch of 285 between Denver and Fairplay myself but I know its high and Fairplay at 10000 feet, Buena Vista at 8000, it drops a bit from there but then your going back up and over the 11000 pass and Durango is at 6500 . So yes your definitely right that 6500 and a lot higher is the theme of going anywhere out in that direction from Denver but hey, the down hill sections give fantastic fuel mileage !.    I don't even look at the fuel pumps for what premium costs here, since I live on a farm and up to this point get fuel delivered I am rarely in front of a fuel pump and when I am, I am often using card lock bulk fuel stations so it tells me what the price is AFTER I buy the fuel. Looking up on gas buddy and converting to US gallons but in Canadian dollars, regular on average of the prices listed was around 5.95 and premium is around 7.00 . That was one reason I did not go for the 6.2 half ton aside from its lack of carrying/towing if one was going by the rule of using premium fuel and until recently one could only buy regular farm gas if playing the few cents off game for farm dyed fuel for a "farm licensed pickup". But yes I hear you on the fuel price difference and like the diesel theme with it often being more expensive then gas it doesn't have quite the charm to it either as it once did although right now here for some reason the price of diesel has come down more so its now inline with the price of regular gas.

      I agree with this assessment. As you know I’m testing longevity with vehicles for the first time. I have a few vehicles I passed to kids and grandkids. We’re all past 100K miles some approaching 170K. I’m the only one doing 5k oil changes. The rest whatever the minder says. I’m the only one doing frequent transmission service. My odyssey the trip vehicle at 200K will be finished as a trip vehicle. I recently changed to high mileage oil, Valvoline. I can’t get past the fact that all manufacturers want to claim long service life. I just don’t make sense that they would go with low weight oil for mileage. While sacrificing longevity.

      Missing thrust bearing? And oil selection

      There's absolutely a mountain of profit in catering to the "I do my own research" crowd, people who are certain they know better. And I don't mean there isn't data to support that 0w40 produces less wear product than 0w20 in an engine like the 3.0 Duramax, that only feeds them the assurance they need. Again, my whole thing with oil selection is, sure, 0w40 or 0w30 produces less wear product. Are we talking the difference between the engine lasting only 100k versus 200k? Or are we talking more like, if the engine will already go 350k on a good 0w20 regimen recommended by the OE, is using 0w40 going to get us to 355k, assuming we can even get the rest of the truck to last that long, meanwhile sacrificing the first 5y, 100k in powertrain warranty. The answer isn't easy, there are tradeoffs.   I willfully use 0w20 Dexos D for this reason, knowing that a 0w40 will produce slightly less wear. I don't believe the delta in wear product is meaningful over the lifetime of the engine, and I place much more importance on driving style and overall feeding and care of the engine as a whole. It's the mentality that someone can abstain from alcohol their whole life which is an amazing boost to health by itself, theoretically. But if they're sedentary, that lifestyle choice will most likely kill them young despite their other, concerted efforts. Maybe someone doesn't drink AND they are the perfect picture of health and activity AND they use 0w40 AND they treat their engine perfectly. If living until 130 years is the goal, sure, do that. But it's going to be a really old truck falling apart around a good engine for that last 30 years, without a doubt.   I watched Demonworks' other video on the 100k+ 3.0 Duramax that had dealer 0w20 changes on what appears to be OLM-prescribed intervals (8-10k).   The QR codes are still present and readable on the main bearings. That's how little wear it has.   That's not proof that anyone else should stick to 0w20, but it's confirmation, for me, that 0w20 is perfectly acceptable to use in these engines.

      1Based on independent testing of OE 0W-20 in the Peugeot TU3M Wear Test as required by the dexos1 Gen 2 specification.
