I am sure it has to do with my (stupid) decision to try OnStar for free, 3 months.
2021 Colorado ZR2 Diesel with GPS Nav

On Sunday - this popped up "SD Card Removed" - it wasn't
On Tuesday: "Warning. You are traveling on the wrong road. Las Virgenes exit in 20 miles"

Except, I was not using any Nav - OnStar or built in. And I had never heard of Las Virgenes road - it's west of Los Angeles.

Has my Nav software gone batty? Still under warranty.

That definitely sounds like a dealer question.

Software update needed. Mine was done last year by the dealer. Mine was showing me going like 300 mph sometimes lol
