I am asking this question to help a friend. He has an Eris and a 2010 Ford Fusion with Sync. His problem is when he gets in car to listen to Pandora it also opens his media player and starts playing his mp3's on his SD card. So he will have both Sublime & Bon Jovi playing (for example) LOL. He can manually close the media player, but when next song on Pandora starts playing it starts all over again and opens media player and begins playing two songs at once. Any help ?
