Random Nav problem

I have gotten this message randomly on my system. Anyone else seen this? Re-inserting SD card does not fix. I have it return to normal at various times.

I assume you formatted it correctly?

I don't think you are supposed to format the NAV sd card. It comes with the car from GM.

maybe a loose connection inside the unit that gets jarred from time to time? Let us know if you take it to a dealer and what they say

Did you look in the center console? The card is there right next to the usb plug... (unseated? Missing?)

Dealer diagnosis

Took it in and based on the code (40000.0112) it is either the card reader unit or the display unit (yikes)! They are ordering the reader unit that is in the armrest console. Don’t know how soon that will come in.

My bet is a corrupt SD card.

Had this in my kid's 18 Terrain (has the same 3.0 or whatever version the C8 has).

They ordered me a new card because they tried to install an SD card off of a stock unit and it was actually mated to the car itself.

Worked for 50 miles then displayed that same message again.

Good luck. Probably just sd card.

Still waiting on a call from dealer with the new part (SD reader), but the damn thing has been working great since.

I assume that if you used Car Play that wouldn't appear.

I think on my wife's gmc the message came up once the infotainment system booted? But it should be a simple fix if not the card it'll be card reader. If only every issue with a Corvette were this trivial lol
