I have a 2007 Chevy Tahoe LT1 and I would like to add the OEM Denso Navigation system that comes standard in the LTZ. I found one on ebay for $1000 and the seller said all need is the 2007 Map CD and a GPS antenna but when I called Chevy to ask them they said I would probably need to add some wiring to make it work. They want to see my truck first. Any comments on this?

There will be one brown plug missing from the back of the nav unit that doesn't exist in your truck. On this plug is a speed sense wire. We add this plug ourselfs when we do navs and run the wire out under the hood to the fuse box on the fender. Under the box are two plugs facing the motor. The plug closest to the firewall has a green/white wire, that's the speed sense wire.

You will need...

the nav

the antenna

the brown plug

the disc

After the install, you will need to connect the truck to a Tech2 to get sound from it...

Mike M2 thanks for the reply! Do you know how much Chevy will want to do this work? Or is there anyone you would recommend that could do this for me. I live in South Florida. Thanks again for your help.

Sorry, don't know about down there. It's a pretty easy task if your even slightly inclined. The hardest part is finding the brown plug somewhere....

Sorry to not start a new thread, but as a new user I need 5 replies first. This one seemed the closest to reply to. I had the OEM Denso Nav unit installed in my 2007 1500 SLT, but the unit did not come with an owners manual. Does anybody know if the owners manual is available for download from Denso or GM? I tried looking on the https://www.mygmlink.com/main/US/en/gm/home website, but was not able to locate it.

 

Again apologies if this was the wrong way to post this question.

 

Thank you.

Hi guys,

I am looking to install the nav system on my 2007 GMC Denali if anyone can please provide me with the spare parts serial number for all the parts mentioned, I would be most grateful. My local dealer wasn't so sure what is needed to install the Denso nav in the car. I told them I heard of other people being able to install it with no problems. He told me serial numbers or part numbers would greatly help him.

 

In addition, is it possible to install the rear view camera as well?

 

Thanks in advance :tear:

Mike M2, I have installed the factory Nav, and now I'm trying to put aftermarket headrest in. They are installed but not any video signal to it. I bought the modified connector for this. My question is do I need to re-flash the nav unit to get a video signal to the headrest?

      My First Project and GMC has me stumped

      By davester · Posted

      are there any codes? with lots of rust, perhaps disconnect/clean both sides of the connection/examine cable ends (the wires) for corrosion going into the sheath & replace if necessary/reconnect ALL the power AND ground cables between the battery, engine, frame, cab, fuse box and starter charm.li (website) has a no-start diagnostic procedure you can work through to get it working.

      OCI, not when but why?

      By Chuck FB · Posted

      Its no wonder you've gravitated to the oil types and brands you have in later years after trying certain brands and one being a specialty oil or at least very hard to come by up here and the other would have been a commonly found oil of the era and the vastly different outcomes as a result to using the vehicles in question the same distance for an OCI . It shows what marketing hype can do without actually having the product to back up the claims and that is no different now with the insane claims that are written on the side of a bottle of oil from some of the off the shelf oils.    What has surprised me and I was already finding this out before I bought my truck with the GDI engine, that this newer fancy technology that seemingly would suggest better fuel economy/emissions with this high pressure spray of fuel is not in reality kind at all to the engine or at least the oils life. Yet they insist on claiming long OCI with this technology just like they did with the port or similar type fuel injection systems when in reality its a step back in oil life to have a GDI system.    I think the mistake your making Grumpy is that your not sending your samples to Blackstone and getting the feel good glowing report that you can run it another 1000 or more miles and then send another sample where they say run it yet another 1000 miles and on and on it goes until your sending in something that looks a lot like road tar and then they may suggest you change your oil within the next 1000 miles 😆

      I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death.

      In the 80's 90's I'd run Honda's 7,500 miles between changes using Red Line HP 5W20 and do it for hundreds of thousands of miles with issues. Back in the day it was an SAE 20 with the HTHS of a SAE 30 and SN add load. It was also very polar. Oxidation VOA was over 120. Besides those motors were SPFI and lean burn tech. I could have likely run it longer but never did.    We had a Toyota bought new I ran on Pennzoil's latest and greatest synthetic of the day with "Penthane". A made up word for a very low dose of PAO. Tried 7,500 mile OCI's in that Group III/VI chemistry and the rings tapped out at 90K. Rocker box wasn't as bad as the one Punch put up but it wasn't good either. Also a SPFI motor.    I'm around 3,750 across the board on these GDI monsters and the oil it tapped out by then usually on TBN/TAN crossover and color. Red Line HP Euro.    The AMSOIL SS brochures tell you to follow the OEM values for the service class but that it can be run up to 25K if monitored. I can't imagine what motor could go that distance and not tap out. I've never owned one.    Yes, I know. Lot's of people do. I'm just not going to be one of them.

      I knew a guy in the early 80's that bought a new Monte Carlo and ran it a 100,000 miles without ever changing the filter or the oil. Just kept adding. It looked like that inside.
