It's actually 2 sources: camera and nav data.
The camera uses shape recognition (it can't "read" numbers), so the database has corresponding shapes to US and international speed limit signs for many variations, like 25, 35, 40, 55, 65 MPH, etc. If it can't get a good read, it defaults to navigation data. Sometimes one or both could be wrong. It's not foolproof. That is why you have eyes.
