I am using Poweramp to play music and the integration is good. It is even displaying Title and Artist in the Navigation Bar.
Only starting the music after starting the car is annoying. It doesn't start itself and it is not possible to start it in the plugin window, because you get a message that the player application is not started yet. So it is necessary to start Poweramp in full screen, then start playback and than you can go back to the main screen.
Can Dudu fix (or the developer of Powreamp) this or is ther an other solution?
