There are different types of USB drivers. Some have a read-only partition for software you have to install to get access to the rest of the drive. It's typically for security or encryption. The Cruze is too simple to play those games. It needs a "straight" USB. The Sandisk Cruzer seems to work well. I tried a PNY, but about one time in 10 when starting the car, it would say it couldn't read it. I'd have to pull it out and re-insert it or shut down the car, open and close the door and restart the car.
