Having some issues with stereo controls on my DX, I believe it has begun since the Gingerbread update but maybe it has happened before too. Sometimes the controls (back/foreward/play/pause) work and sometimes not. Today I played with it a while and noticed if I had the bluetooth on before I started my car (2010 Mazda3), it would work every time. But, if I waited till after my car was on it would not work. I keep the BT off to save on battery and have a car dock and setup to turn on BT when connected. Not the end of the world but annoying.
