Sd card

[Macktes]

Hello, I bought my 2021 Yukon at4 from an auction and didn’t come with a sd card. Where do I buy one? Does it have to be a certain card?

If you are talking the Nav Card, it kind of varies. The part number for my 2020 AT4 is 86775533.

I bought it from a used dealer and the SD card was locked up (stuck in another vehicle). Once they are stuck in they are locked to that vin.


When you program it (stick it in the SD slot), make sure you cars power is completely off. I left the power off, key out of the car and door open for about 10 minutes. After that I stuck the SD card in and started the engine. You will then follow the prompts. Just a few questions.
