SD card message

SuperDuper · June 19, 2019

I have a 2019 AT4 that every time I start the truck and select Nav, I get the following message:

SD card message: Once initialized, this SD card can only be used for navigation in this vehicle.

My my only option is to hit the confirm button on the screen and then my Nav map will load with no further issues. Does anyone know how to clear this message so it doesn’t show up every time I start my truck. Thanks in advance for the help.

Mine did that and once I set up a user it went away.

Thanks for the feedback. I did set up a user profile on my truck recently, but am still getting the message.

There is another thread on this. The problem is that the card is locked and cant be written to. The truck is trying to initialize the card and write data to it but it cant. Floppy disks used to have the same thing back in the day.

Pull the card out and look on the side. There is a little tab. Move it to the unlocked position, put the card back in, start the truck, and then it will happen more time, press confirm, and you shouldn't see it again.

Same thing happened with my truck.

Thanks very much for posting this. Duh on my part.

After updating to 807 and replacing the SD Card and card receptacle, GM now wants to replace the radio control module, which requires two visits, one where they need to get the number off the current unit and another to replace same.

I want them to go to back to 509, the last known working version which had no problem at all.

Has anyone been successful in getting a dealer to go back to an earlier software version?

Any other updates anyone? Please provide the latest status.

Thank you.

I am having this same issue. My dealer too wants to replace the radio module. I am not thrilled about them tearing apart the dashboard in my 9 day old 1500 Denali. Has anyone had any luck in getting this issue resolved? Currently, the SD card has been replaced as well as the SD card reader. Anyone able to help?

Similar issue. SD card removed error randomly occurring riding down the road. Not all the time. However, I could make it happen error by disconnecting the USB cable from the truck side outlet. At which point the USB ports (dash and console) were dead (no power; no Apple Carplay) until some time later usually sitting overnight. Dealership replaced SD card today....didnt fix it. So I demonstrated the issue to the tech, so they took it back again. After an hour of waiting this morning they are replacing the radio module (I think). I was told the dash had already been taken apart, so they gave me a loaner. New parts to arrive on Monday, so we'll see if its fixed then.

Hoping this fixes the issue, but I am going to be meticulous in making sure none of the trim is scratched or loose. Only had the truck for a month...

Hello everyone. Hope all is well. Any updates on this anyone? Please do advise soon. My best.

I just got my 2021 AT4 and was getting this same message and unlocking the SD card did the trick. My question is why was it locked to begin with, is this something the dealer did inadvertently or did it come from the assembly line this way. Anyway, my problem is fixed thanks for the post.

I am having the same issue. I have a 2021 AT4 with 600 miles on it. The dealership told me that the SD card needed to be replaced. So they are ordering me one in. At the same time I had a check engine light come on and on star told me it was throwing a P00C7 code. I had a 2019 AT4 and had nothing but trouble with it. The dealership told me that it was uncommon to have this many problems with this truck, that’s why I traded for a new one. Now I’m having problems with the new one already. I’m starting to loose confidence in GM.

Where is the SD card located? Please and thank you!
