App works but not well with AppRadio 2 and 5S

This app only works if I kill all apps then I have to open AppRadio first before I can use this app. Just to listen to my music. If I leave my car then return without killing the app, it just displays on my AppRadio 2 as a mirror of my phone and I cannot control my music. Whats the point of an iPod icon on home screen and you cant control your music, Pioneer. Fix it please.
