My USB CD player does not work
FIRST, make sure you are plugging it into the USB ports under the radio that are up front. If you are plugging it into USB ports on the back of your console that are for the rear passengers, it will not work (these are power only, no data connection to the radio).
SECOND, The eject button is supposed to be under the CD slot. Data side (shiny side) of the CD should be facing the eject button. Label side should not be facing the eject.
THIRD, Try a different store bought original CD.
