Sign Recognition Not Working

[Big Mama]

My 2023 Sierra has HUD but the sped limit sign is blank. I thought it had something to do with my OnStar not working but I found out it works by using one of the front camera.

I’ve gone in the DIC menu and made sure the option is on and that the front cameras are clean. I feel like if it was the camera it would work from time to time, which isn’t the case. It hasn’t worked since I got it in August.

I read about clearing the cache in maps but I’m not sure how to do that.

Any help is appreciated.

I was not aware this was a feature but this is what it says

Thanks Wes, I didn’t know that was a thing either. What I’m hunting for is called traffic sign recognition. On the driver display and heads up display there’s an image of a speed limit sign that’s supposed to display the last sign the camera saw. My display shows the signs, they’re just blank white squares. I’m going to try that other feature tomorrow.
