If you install you may have a bunch of lights on like CEL, etc...
Once they do the included directions they will all go off and work normally.
Just make sure they ONLY do what is wrote, if they try to program it WILL wipe it!
I just updated my radio and Y175 is the latest. I think I was at Y171 before.
Not sure if this is a OTA or only dealer installed update.

I did it myself so I just had check engine and other lights on (I have a MDI2 and Delco account for my Tahoe). So you will probably just have a bunch of lights on, but the tech will plug in and they have to run a command which will reset all the lights then clear the DTC's and will then work...
Yea, plug and play as they set it up to your options but you need to have a dealer plug in to do a quick setup or if you have access to a MDI2 and account you can do it yourself. They give the directions on what needs done, very easy.
There was no options in drag software to do anything with them. I had to go into the module and actually remove, I could not even just delete one key or rename it to #2.
GDS is the Diagnostics System. Did it today, used SPS. You have to "delete" all learned fobs, you then learn each one. I went from 3 to 2. Worked perfectly. I have the SPS for 2 years on my VIN, just needed a MDI 2 interface.
I am having the exact issue. Bought a 2021 that came with one key, had dealer program a new one and it become fob 3. from what I am reading (because I also need to fix this ) you have to take it to the dealer, they will delete ALL fobs out of the immobilizer module and re-add the ones you now...
Got a used 2021 Tahoe that came with one key fob. Had a new one made for it but it is considered "Key Fob 3" so I can't save seat position#2 to it.
How can I delete the old Key Fob that is missing so I can set my #2 profile?
I do have a TechLine Connect account for my VIN and J2534 Bosch...
Ok, I purchased my own used Full Digital Cluster from a 2023 Tahoe (no HUD), I installed this into my 2021 Tahoe Premier. I usedACDelco TDS and serialized the new cluster to the system and it works perfectly. My only issue is that I no longer have the HUD working, I know it needs to be...
I have a 2021 Tahoe Premier and looking to see if there is a list of the updates of the software so I can check my version. I heard you have to goto a dealer for the updates now and they are no longer OTA so I wanted to check first if mine even needed one.
If you look for the radio module by google or eBay ( https://www.ebay.com/itm/256489344073 ) you can get these for $200. This is the module I believe that would have the newer 2022+ google maps, etc on them. I am guessing it would not be as easy just to purchase this receiver and install in...
