I don't think that's true. See Gracenote's FAQ

"On most commercial music compact discs, there is no disc title, artist, track title, credits, or other information"
The way it works I think is based on just the length of the tracks. It looks in its database for a CD that has those exact track lengths. So for newer CDs, you need to have a newer database. In a car though, I don't think they have a way for customers to update the database on the car's hard drive.
