TSB: Toyota models equipped with the Premium HDD Navigation (AVN/AW-EMV) system will periodically require an update to the Gracenote® database. Gracenote® includes detailed information for songs (genre, artist, song title, album name, etc.). The Gracenote® update will be included on the USB Drive Navigation Map Update SST. A Gracenote® update must be performed before a Navigation Map update. A Navigation Map update is not required to complete the Gracenote® update. Use the process described in this bulletin to perform the update.
