For the record, the IOS entertainment system is listed as standard equipment on the Trail Boss package, my truck has the SD reader in the center console, and the build sheet for my 2019 Trail Boss says it has the IOS entertainment package. So there is no question that I should be able to add the factory navigation to my truck.

 

As a side note, I have tried and for a wide variety of reason do not like any of the current Apple CarPlay / Android Auto solutions. So while some may disagree with my objective here to add OEM nav to my truck (and might even in a futile effort feel compelled to try to change my mind right here on this thread), my mind is made up and I want the factory navigation feature on my truck.

 

As many others with this same configuration on this forum have done, I surfed to my favorite authorized online GM part houses, keyed in my VIN, and confirmed that the "IOS Nav Upgrade Kit" "fits your car". Being confident that I could follow the trail blazed by others on this forum, I pulled the trigger and ordered one.

 

Unfortunately, that is where my problem starts.

 

When I contacted my relatively new metro-Atlanta dealership (let's call them dealership #1) to arrange to have the vehicle flashed, I was not surprised that they were unaware that it was possible to upgrade my truck. So I provided them the link to this forum showing how it was commonly done, and the link to the authorized GM part house showing that "IOS Nav Upgrade Kit" "fits your car".

 

After a considerable amount of time, dealership #1 eventually came back and said that they had contacted GM and that it was not possible to upgrade the IOS entertainment system in my truck, and they further explained that GM did not want the liability of supporting these upgrades and suggested I look at the gm-navigation.com aftermarket product as an alternative. When I looked at the suggested alternative, it appeared that all they are doing was flashing the GM module, convincing me that maybe I needed a second GM opinion.

 

Enter dealership #2.

 

Dealership #2 is part of a large national dealership group. Certainly, I thought, they should know how this is done, and on the remote chance that they didn't, they should certainly have GM connections that dealership #1 might not have had. So I reached out to them, and it was no surprise when they responded back almost immediately that yes it could be done, stating "If the code came with it, we should be able to program it. The cost to do it, is $243.95, that includes the $100.00 that GM charges us for the Download. We would need the vehicle for 4 hours."

 

However when I asked for some detail about the "the code", they replied rescinding their earlier statement stating that "... there is NO Upgrading of a Factory Radio to add Navigation! I checked with our Parts Department and they confirmed this as well. I don’t think even going aftermarket, if you can get the Navigation to work, I believe you lose some of the functions of the Radio."

 

So here I am. Has some type of edict been handed down from GM? Hopefully, some GM tech out there can shed some light on this very confusing situation.

Just for future readers, this is incorrect. LT Trail Boss comes standard with IOR. You need Convenience Package II in order to get IOS.

Do you actually have the IOS radio?  Can you either pm me or post the last 8 of your VIN number? 

 

If so, GM did have a nav upgrade but they have discontinued it.  You can still get it, p/n 84531832 you just have to find a dealer that has one or can still get it.  GM still is supporting the install as far as I know too.

Yep IOS (just wanted to make sure lol).  And if I read your original post correct again, I assume you have in your possession the GM upgrade kit p/n 84531832 ?  If you do, it will have the SD card and an authorization code sheet in the package.  A dealer would then call GM Techline with that authorization code, and then GM will make a calibration file for any necessary modules that have to be reprogrammed, in the case of 84531832, its typically the IPC (the cluster) and the radio.  Dealer can find the instructions in GM Service information, doc id 4858827.  Its titled "Navigation Data Card Package Installation (Instruction ID: 84190854)."  

 

If you don't have the 84531832 kit, you will need to get one. 

 

I do know that 2020 folk are out of luck as there is like 10 of the 2020 # in stock nationwide and it too is discontinued by GM.  We did a 2020 last November and it was a smooth install, except for the fact that we had to wait 2 days to get the calibration files as GM didn't have the 2020 ones ready yet.

What was the part number for the 2020?  Any idea why they are doing away with the upgrade?

84489271.  Not sure their reasoning for dropping it.

The good news is that the 2019 GM upgrade kit p/n 84531832 is still available (more than 100 in stock), and suburban Detroit dealership #3 confirmed that they can get it to me in one business day. The bad news is that while dealership #3 indicates that they know how to do it, have done it multiple times, and would love to do it for me, they indicate that for some unknown reason, GM is now saying that this part is incompatible with my VIN - even though their own online VIN checker says that it is compatible. It may be a technical issue, or a marketing position, but either way they don't know why GM is taking this position and are not willing to take any chances.

 

So now that all three dealerships have taken the same position on this, have I struck out, or is there a GM tech out there that can shed some light on the situation? What is special about my VIN.... is there anyone out there that has upgraded a 2019 Trail Boss that came with the IOS entertainment package?

Did they actually call GM Techline to try and get the truck calibrations?  It sounds like they are just relying on the accessories catalog and saying its not compatible.  The GM Accessories catalog that the dealer uses constantly has parts removed, updated, etc. so things won't show up in there correct.  I always have to double check info on there as its always down/broken/numbers change.  

 

Unless...GM is no longer supporting the upgrade and Techline isn't doing the upgrade.  I wish I had a truck here to test this all out on but I don't unfortunately.  I might later this week though as I had someone call about this on Saturday.  

 

Here is the GM EPC with your VIN showing the card as compatible.  Note your IOS radio code is highlighted which indicates a matching part based on the VIN.  If you didn't have IOS radio, the card wouldn't even come up for me.

Good info newdude; I certainly now have a lot of info on my side that the average consumer would not have.

 

Thanks very much.... I will keep you posted!

I've checked online and no one seems to have the #84489271 conversion kit. Do you know where I might be able to get one of the few remaining kits?

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That makes sense, and I think you are describing the real product problem. Capturing data is the easy part. If the owner or technician has to manually dig through five minutes of millisecond-level logs, the product has already failed. The device would be at the ECM harness, not at the OBD port, so I agree that data retrieval and event marking need to be thought through carefully. The way I am thinking about the architecture is: The recorder itself should not depend on a phone, app, Bluetooth, Wi-Fi, or cloud connection to capture the event. It should always keep a local rolling buffer and lock the event locally. A button, phone app, or small cabin device would only act as an event marker. If the driver feels a stumble and presses the button 10–30 seconds later, the pre-buffer has to already contain the useful data. For data retrieval, the practical options would be a sealed service USB lead, Wi-Fi download, or a phone/cabin companion device. I would not expect the owner to remove the ECM-side module or work with raw files directly. The cloud or AI side would be for interpretation, not for capturing the event. The truck may have no connection when the issue happens, so the evidence has to be saved locally first. After that, cloud processing could help decode the data, compare it against baselines, and generate a readable report. For the first version, I would keep the automatic triggers conservative and objective: driver event marker bus-off error passive voltage drop / brownout device reset FIFO or queue overflow a normally periodic message disappearing side-to-side communication mismatch, if the topology supports that For “learning normal,” I agree with your point, but I would not want to overclaim it as automatic root-cause diagnosis at first. A realistic first step would be learned baseline comparison for that specific vehicle and operating condition. For example, a value would only be compared against similar conditions: RPM range load / MAP throttle position gear / vehicle speed coolant and oil temperature battery voltage AFM/DFM state, if decoded and validated Then the report could flag things like: this periodic message disappeared compared with its normal timing this value deviated from this vehicle’s normal range under similar conditions the same abnormal pattern repeated after the same type of event the anomaly occurred together with voltage, oil-pressure, misfire, or communication changes But I would still call that “abnormal pattern detected,” not “replace this part,” unless there is enough validated repair data behind it. So the intended product would not be “here is a huge log.” It would need to be an event package: what triggered the capture how much pre/post data was preserved what changed before and after the event whether the device itself reset, overflowed, or saw a bus error selected graphs around the event raw data only as supporting evidence From your perspective, what would make this kind of report useful instead of just another datalog? For example: What are the top 5 parameters or events you would want highlighted first? Would you trust a learned baseline for that specific vehicle, or would you prefer fixed thresholds? How much false-positive flagging would be acceptable before you stopped looking at the reports? What would a one-page report need to show for an independent shop to take it seriously? For misfire, AFM/DFM, oil pressure, or U-code complaints, what would you want the tool to flag automatically?
