I was able to find an SD card with an authorization code.  There are not many left in the system.  The dealer was able to get the NAV software installed but it says there is no SD card when there is.  Also, the USB  the center console no longer works.

 

My dealer is working to figure all this out.  They are attempting to warranty the Nav with GM.  I hope to find out something on Monday.  
 

I have seen my issue repeated a lot, and that is my guess as to why GM quit offering the SD card upgrade.  If I were doing it again I would use the gm-navigation.com option.

The Dealer told me that they charge 600.00 to install card and program. Card part # 84489271 is an active part number, the service tech after talking to shop tech and GM told me if I buy the card it is pretty much plug and play. But others say this is not true the dealer must set up or person with Tech membership or MDI. I am left confused by all the double talk.

The kit # 84489271 comes with card and book with instructions as well as code number for GM assistant?

I went through all this recently.  My dealership was also confused.  

 

My truck had the 8" display but no Navigation.  As part of my purchase I bought the Nav upgrade for $500 (this was in April).  

 

It was very hard to get the upgrade kit.  There were only a few in the system and the dealers who had them didn't want to sell them.  They wanted to keep them for their own customers.  My dealership did not find one but I did.  An out-of-state dealership had a kit on hand they had ordered for a Tahoe.  The Tahoe was wrecked in transit so the sold the Nav Kit to me.

 

My dealership had to first install the Nav software.  To do that they needed the authorization number that came with the upgrade kit, and and they had to use the Tech II or whatever tool they use now to install the software.

 

When  the Nav software was first installed, the software couldn't read the Nav SD card.  So my dealer ordered a new card as a warranty replacement.  It got lost in shipping so they ordered another.  Unlike the complete upgrade kits, the SD cards were readily available.  When the replacement card finally arrived the Nav still didn't work.

 
So they did more testing and discovered the card reader was bad.  After the card reader was replaced the Nav system started working with the original SD card that came with the kit I bought.

 

It is a very good Nav System.  It just took a while to find the kit, troubleshoot, and get it working.

so the card does work without having to change the module like aftermarket companies do?

 

I now have an LT with conv 2 pkg so I have the sd card.....seems easier as long as dealer knows wtf they are doing

i have a 2020 chevrolet silvarado lt trail boss and i wanted to get the navigation up grade check around,if you get the navigation sd card you still got to to take ta dealership and get your infotainment system flash for the navigation app,then hopefully you want have a issue with the sd cardnot being able to bring up the map.if you go to oddgenie you can get a gn nav programer for that will do what the dealership will be doing for 499  and you can reuse  if you ever have a issues and lose the app if you take back to dealership and they do a update and you lose the nav  app on your radio you can flash it back on instead of paying the dealship to reflash .right now i have a issue and i,m calling them to morrow i have the nav app but it want pull the map program up keep telling me to do a restart.that why i think gm decided to get away from these nemory card nav app causing to many problem getting to work right

There are a lot of cards out there for sale.  Yes, You really only need the card.....However....There IS an activation code that you need when the dealer does the FLASH on the ECU.   Without the code...the card CAN NOT BE INSTALLED AND ASSIGNED TO THE VIN.

 

Spent hours going back and forth with the dealership....even the GM Instructions clearly show...when to enter the activation code in the FLASH programer to activate a NON NAVIGATION vehicle.

 

To be fair....All the IOS 8" Infotainment systems HAVE THE NAV built in, it is not activated...YES, you need a new, unused/unassigned card to make this work.

 

When you buy the kit from GM...and it is still available for just under $600....it comes with the card...and a code....Not much of a "kit", but it will allow the tech to flash the ECU

 

The online reseller that requires the core....has the cards and codes...he takes the return units, installs the code in the ECU during the flash in his facility and sells an operating module....true, he agrees there are some issues with the On-Star and the ECU "talking" to each other....does not offer a solution to these issues.  So you buy another ECU... swap it and return the core for a credit.  Then deal with On Star and XM to have them change the serial numbers to re-activate the new ECU serial numbers/codes to return the satelight radio to operational mode.

 

It is NOT....Simply installing a card and flashing the ECU.

 

I am neither a GM employee or Tech....Simply a customer who went through the entire experience and expense to learn the hard way....buying the "card" does not install NAV.

 

Just my five cents!

Just want to make sure I am clear,  the card that you are selling do not have the activation code?   I am think sometime down live I want to activate the internal GM map software so Want to understand the options.

The card he sent me did not work. I specifically  asked if was plug and play and if the dealership would have to get involved, he guaranteed it would work. I have since tryed to ger my moneyy back but he refuses. Thats where this stands.

Thank you for the update, so it sounds like he did not provide a activation code with the card.   I am going to add SD moduled to the system with the hope of later down line having the Navigation system activated by the dealer or MVI below.

Correct me if I am wrong here but the navigation cards( with activation Code) are now showing up as available to buy again.

      Some Assembly is Required

      By Grumpy Bear · Posted

      www.enginelabs.com/news/what-i-learned-today-bearing-clearances-vs-oil-viscosities/     www.enginelabs.com/news/oil-viscosity-can-the-numbers-be-misleading/ The Big Lie… Coming full circle to the reason Lake discusses the Porsche engines in particular. Based on the 2000 samples in the SPEEDiagnostix database, increasing the oil viscosity in these engines, even those run on the track, showed no significant difference in results.   The smoking gun was in the oil chemistry. That is where the data shows higher instances of more wear. Molybdenum was the key; the higher the amount, the less the wear. Speed postulates that higher viscosity oils have more thickeners to artificially inflate their viscosity numbers. These thickeners lose viscosity under shear, and the result is that not all oils of the same viscosity have the same shear stability.   Having enough viscosity is the most important characteristic, but according to Speed, once that required viscosity level is reached, additive chemistry matters more than additional viscosity. Speed also states, oil pressure problems on the racetrack aren’t a viscosity problem; it’s an oiling system problem. Running a thicker oil is just a band-aid for an underlying oiling system problem.

      Some Assembly is Required

      Can it still be Assembled II?   Viscosity on the decline by various means. Heat on the rise making that worse. Engine RPM in the tank. Smaller motors with more boost trying to emulate an electric motor. Full torque, zero rpm. Then we will triple the OCI. Argh.    But wait....there is more. LSPI has pushed a shift from Ca to Mg and as that cost more PLUS the run to lower sulfur compounds the TBN is moving in the wrong direction for the increased OCI's demanded.    That not being enough to placate a demand for a parameter they can't measure the other sulfur bearing compounds are also under attack. That would be zinc and phosphorus sulfonate compounds. To some degree those are being replaced with boron esters and others, i.e. titanium ect. All of which have shorter service lives. And there there is the "Secrete Sauce" marketing for AW adds that 'Can't be detected by UOA's" but trust me because I (the blenders) never ever lie.    Spoiler alert; ALL additives are sacrificial! Smaller amounts of the old blended with less robust versions of the new do not equal longer service lives. So what are the blenders recommending? Wait for it.......   MOVING THE GOAL POSTS! OMG      Let's declare the long standing TAN/TBN crossover irrelevant and tell people that soot is a great 'graphite' based lubricant which can aid tribo films. Wait, what? Let's declare that the standards used for oxidation and nitration were to conservative and can be expanded. Let's tell them that because GDI fuel dilution, although being a VISCOSITY KILLER and an acid generator is actually okay because we have better base oils that limit viscosity failure limits. (Said knowing this is measured in fractions of a centipoise and in bases not commonly used in shelf oils)   Lying from the heart is not just the new normal but we have a public, a very young public, that is so ignorant of the facts and so sure of their "RESEARCH" into AI driven models base in regurgitated  instead of scientific research based unvarnished, peer reviewed FACTS that the incoming guard is loosing their grip on reality and the OEM's are tickled pink while the blends bend the knee.    You have an ever limited set of tools to work with. And sooner or later those will be taken from you as the API and the EPA strangle the last remaining fluids from the system. What you have left is your wits. If you care to use them.    At some point in the very near future it will not longer be possible to do "What is best for the machine", and be replaced with "The best you have access too". You WILL be rewarded with half the life and twice the cost. That isn't that hard to predict.

      Software Update

      By Chuck FB · Posted

      I trust you saw the other comment where he knew what he was talking about !. Yes, these darned newer vehicles with all their so smart they are stupid technology, goes and drains the battery down. As you might see my other comment, I installed a Noco 5 battery tender under the hood and at this point still have the cord routed so I have to lift the hood and then plug it in but am typically parked in a garage or a shed so its not risking the engine hood in the wind. That way I am assured or hopefully so of not finding I have a battery drawn down and can't even start the truck and that also damages the battery to draw it down too far.

      Software Update

      By Chuck FB · Posted

      I guess no surprise my guesses were wrong !, at least now I know if I ever happen to see it grayed out in my own truck as to what is going on.    I never happened to catch my truck with it grayed out, it seemed every time I would test to see if there was an update it never found anything and yet more than once I would check to see if there was an update and there was nothing, then a day later or even that same morning I would drive to town and after more than one engine shut down in town as I did my errands it would pop up that there is an update now ready to install and the only place I have a connection to the internet is at home by wifi so its not as if it grabbed the download while driving. I don't trust these new vehicles due to all the crap they can decide to do while sitting for some days not running and run the battery down so most of the time if I know the truck will sit for a few days I plug in the battery tender I have mounted under the hood and so the only time the truck must have downloaded software was when it was sitting in the garage where the signal is awful but I have that tender plugged in and somehow it managed to download it. I honestly detest all this crap, way to easy to leave a person stranded.    Since I don't trust any of it I don't do the install of the already downloaded software until I get home and sometimes have even sat in the truck to watch what its doing as its going through the process to its conclusion as its not like it is set up that it will tell you the next time you fire up the engine that the update that was initialed actually installed or installed properly. Yes I can go into the updates and see the list. After I go through the install where I feel its safe to do so in case it breaks down as a result, I will plug in the battery tender after the fact to recharge as I don't know how much power its taking just to do the install and that can take a while for it to install.

      Software Update

      Thanks for the reply. All settings were correct and the engine was off, as it was supposed to be. It turned out to be something simple. I took a drive for about an hour. I must have had a low battery without knowing it. The voltage gauge on the display looked ok. At the end of my drive, I shut off the engine and the update prompt came up and it updated normally. It’s ironic because one of the features of the update is a reduction of battery drain.
