Can you "DIM" the display with your dimmer?  This is done through the data wire as well.

Yes, it dims just like the rest of the dash. It does seem like the Hu is communicating. I don't know what else to do other than send the Hu in to Delphi or some one to have it checked, unless someone has another suggestion.

KDC Racer, another thing to try if you didn't think of it.  If you have a code reader.  Set up a DTC by pulling a key fuse somewhere, and see if your port is communicating.  Can you remove the code, etc.?  If you don't have a reader, autozone will lend you one.

I'll try it. I do have a code reader on my PDA. I assume it needs to be a BCM related fuse to see if that port is working, right?

If it is an 05 TNR, some of those can not be unlocked by a tech II without being in the donor vehicle and those can not be placed in another vehicle.

Does anyone know the part number for the 2 harnesses at the AMP? or more specifically, part numbers for the connectors themselves and pins?

 

Thanks

I have the harness for the 6 disc changer and made the solder connections to the 24 pin connector. The spaces for connecting the remaining 3 wires to the 12 pin connector are already being used. What do I do? Thanks.

Splice the wires in using soldering or Scotchloc connectors. So, in other words, tap the 3 CDX audio wires into the appropriate wires that are already in the 12 pin connector. These wires that are already in place are for the XM and/or RSE. Because the GM head units only actually have one physical aux input, the different aux devices are simply all wired into the same input (in parallel) and the Class II data bus determines which device is on and off, effectivly "switching" between the 3 possible factory aux input devices (XM, CDX, RSE).

BBSilverado--- What do you mean by "some '05 TNR's can not be unlocked with a Tech II"?? I have a '0099 lux TNR / upgraded Y91 amp that I put in my 2005 Duramax crew cab and it all works fine, but then again, I bought the nav NEW (no tech II needed). I am now paranoid that one day the Theftlock will activate randomly (ive heard of this happening) and I wont be able to unlock it!! (because a nav unit is not a OE option for my vehicle) Would I be completely out of luck with a useless TNR?? :rolleyes:

Thanks Ben. I'm also nervous because I thought I bought a used '05 TNR and did not have to have it theftlocked. Or the seller screwed up and sold me a new one.

Hi Guys, Great bunch of info on this topic, But I still have a few ??s.

 

Could there possibly be a warranty issue concerning GM not covering the NAV unit as most of our trucks are not coming factory equipped this way? or worse yet, GM not covering any possible electrical malfunction and placing blame on our install, even though factory equip is being used?

 

I had a service manager tell me when I switched over to the power tow mirrors, that I could possibly fry my BCM and GM would not cover because I was installing mirrors that originally did not come with the truck from factory. Just a thought.

 

I'm sure thousands have done mirror swaps as I have with no problems, but this head unit is big coin and wouldnt want to have something go wrong and probably not be covered.

O.K. just thought of another few??s.

 

If I decide to do this mod and go non lux version as I have dumb amp and 6 cd head unit with bose. Are these part #s correct?

 

10377287- TNR

15135178- GPS antenna

15312903- CD changer harness

15122617- In dash CD changer

12089649- GM Terminal ends

 

VSS wire taps into A4 position at gauge cluster and goes to E position at small 12 pin connector on head unit? CORRECT?? also if there is already a wire in E position due to onstar we just splice into that wire correct?

 

Now for the complicated question. I already have an aftermarket DVD player in my dash pocket playing monitors in my head rests, can I watch video on the nav unit as well? what adapters may be needed? part#s?? I also wish to add a backup camera and want that image on the NAV unit as well. Can both options be done??

 

 

I am also now realizing that I would require the 6 cd magazine type changer as I do not wish to move my DVD unit. I would also require a much longer harness. Anyone have those GM part#s? Thanks.

 

If by chance I get lucky and can add everything I wish to do, Can someone also tell me how to hook it ALL up. I feel I can do the NAV unit, just not sure on how to hook up the possible extras.

 

I WISH TO THANK EVERYBODY WHO HAS CONTRIBUTED TO THIS THREAD, FOR I WOULD HAVE NO IDEA ON WHERE TO BEGIN IF NOT FOR YOUR INFO !!!!!!!!

 

Also sorry for the long post.

New units do not have a VIN stored in them, so when it is installed and powered up it will learn the VIN of that vehicle. Used units will have a donor vehicle's VIN stored in them and will lock up if the unit is placed in a different vehicle. In most cases the TNR can be commanded to learn a new VIN but that can only be done once with the Tech II programming after that the unit has to be sent To a Delphi service center (I don't know what they do with them at that point but it is more than what can be done by GM service programming)

I have never heard of a newer headunit (03-05) weather a nav unit or regular radio randomly locking up, the older (pre 03) units did do that but they where theftlocked by a user assigned code and not by encoded VIN's. The older HU's would lock up anytime the power was temporary lost and the theftlock option was turned on.

Your part numbers are correct.

If the wire in the "E" postion is purple with white tracer then you do not have to add that wire from the gauge cluster.

The nav unit will not display video as it is now, but a video input interace is available to enable it to do that. the interface will only add video to the screen and not audio. The interface requires you to take the nav unit's cover off and remove a ribbon cable and install a new cable that connects to the video input adapter and a dash mounted switch (the switch allows you to select input video or the normal display from the nav unit)

The video interface: http://www.carmobileaudio.com/product/PACVCI

You would then need another input adapter for the audio on your DVD player (you won't need anything if your just using it for a backup cam)

If you are going to use both (backup cam and DVD) then you will also need a video selector switch installed so you can select between the camara and the DVD player.

Everything you want to do is possible but it won't be cheap, the video input adapter alone is over $350.

Group,

Thanks for all your help. I was able to install the 05 Nav unit with no problems. I am waiting for the GPS antenna and CD. I just wanted to let you know that the dealer shows that the v3 disc has been update with part number # 15105609. I will let you know if it is an update when I receive it. Also can I take an Alpine CD changer and splice it into the system?

 

Thanks again…

There is no concern that it will void your vehicle warranty, but GM will not cover the nav unit itself. You did not buy the nav unit from GM so they will not warranty it. If you did buy it new from a dealer or retailer you should have a warranty on the unit through them. I got a 1 year warranty on the one I bought through Model Electronics.

      2015 Silverado 3500 right rear turn indicator failure

      By davester · Posted

      consider doing electrical testing?  I would guess some power or ground wire/connection has a problem.   alldata.com has wiring diagrams, connector pinouts and diagnostic procedures you can use to find where the problem is.

      My First Project and GMC has me stumped

      By davester · Posted

      can you tell if the reader is actually trying to get codes, and the pcm is reporting none, or is your reader just silently failing because it's not communicating with the pcm?

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

      By Atlas · Posted

      Any joy with this truck seems to be short-lived.   The CEL for P0172 ("bank 1" too rich) is now "intermittent".   I'm not sure where to check, or re-check, and my energy to keep chasing problems with junk is wearing thin. The P0172 seems to set as I'm coming to a stop, completely off the throttle, when fully warm. At least, that's what it's done the 3? times it's set.   Everything appears normal on the scanner EXCEPT long term fuel trim. There's only one bank on this vehicle because it's an OBD 1.5 with only one upstream O2 sensor. At idle, it's around -16.4% and will dip to -18% occasionally at idle or off-throttle. LTFT approaches 0 when throttle is held at 2500rpm. Short term appears normal, much closer to zero all the time. The LTFT tells me the engine is running rich at idle but compensating at higher load. But, why?   The EVAP purge valve doesn't appear to be leaking/sucking fuel vapor continuously. Is it sticking just as I come to a stop and the engine is choking on fuel vapor and sets the P0172? But that doesn't explain the persistently negative LTFT. Disconnecting the purge valve doesn't seem to make any difference.   I suppose that leaves another dang issue with the fuel injector. A leaking fuel pressure regulator, a new leak in the spider, or a leaking fuel injector/poppet valve I didn't see, or a small crack in one of the spider legs.   The vacuum line leading to the fuel pressure regulator doesn't have raw fuel in it. It doesn't even smell like fuel when it's pulled off, not until you suck air through it, then you can tell it leads to a fuel component. I'd consider that normal? Nothing is signaling this is a FPR issue from the outside, at least.   The oil smells like fuel but it's not building volume. I've noticed most oil in most engines smells like fuel to some degree so it's hard to say if the smell is an issue or not. Or if the engine just still smells like fuel because the crankcase was full of it a few hundred miles ago. But it's been changed twice since that original issue of the leaking fuel line dumping fuel into the intake.   Patience is running very thin. Every win seems to be accompanied by two steps backwards, or another issue that leads to removing at least the top half of the intake manifold. Enough! LOL

      Tire pressure for 37s

      By Chuck FB · Posted

      First off you mentioned "Toyo Says" and then gave the pressures 45/50, was this some person at the tire shop that pulled those numbers out of his head ?   Now of course I can't know your exact axle weights front and rear, however I have much the same pickup as yourself other than not knowing your starting weight as per the pounds the truck rolled out of the factory at due to the options yours did or didn't come with or what you have added beyond the extra tire weight. The correct way to know 100% where a person is at is by weighing each axle with the typical weight the vehicle is driven with and that means taking into account passengers and making sure you figure in a full tank of fuel and a little grace for whatever you may put in the bed "groceries" !    I am looking at and not that it really matters as all the tire companies use the same charts anyway, but I am looking at the comprehensive Toyo tire chart in the section that your tire falls under and I know it sounds confusing but your tire is not an LT metric tire like your factory tire but instead because its a standard inch measured tire its under a different category called an LT floatation series tire. That makes a difference as LT metric tires they don't want to see run below 35 psi at highway speed where as with the LT floatation series it can be run down to 25 psi on the highway as long as the weight on the said size of tire is agreeable with or less than that minimum 25 psi. It blows many people away that how is this physically possible, an empty truck for one thing and larger tires with the same size wheel diameter have a lot more air volume so they can carry the same weight as the smaller tire with less air pressure.    So my truck, I have the stock 275/65R20 wheels and tires and I have a bit of weight in the box with a bak flip cover and a rubber bed mat and some tools and spare gas. The front of my gas truck weighs a bit more than some trucks of the similar spec due to double batteries and alternators. However with full fuel and just me in the truck I am weighted such that I can run 40 front and 35 rear and so that is what I have done since day one.    If I base your truck at or slightly below the weight of my truck, in theory with your tires going by the tire chart you might be right around a minimum of 30 pounds front and 25 pounds rear. Of course that would hit pretty much minimum cold inflation pressure one could run with that tire size and a near empty truck. If you have access to an accurate weigh scale to do individual front and rear axle weights I would suggest you do that and make sure your topped up with fuel and whatever else in the truck before you weigh it and then you will have a great starting point to work off of and figure out what your bare minimum pressures are you can safely run. If you do much in the way of hot weather high speed driving, bumping up a bit for a safety margin is never a bad idea but just depends on what type of driving you do. I will include the Toyo chart and the floatation series sizes start on page 31. Without a doubt at these pressures I am speculating at minimum wise for your truck, it would most certainly ride very different then it did when you were using 55 lb front and rear.     https://www.toyotires.com/media/pxcjubjs/application_of_load_inflation_tables_20200723.pdf
