When the temperature returns to normal, the CD should play. • You are driving on a very rough road. When the road becomes smooth, the CD should play. • The CD is dirty, scratched, wet, or upside down. • The air is very humid. If so, wait about an hour and try again. • There may have been a problem while burning the CD. • The label may be caught in the CD player.
