iOS updated to 8.1, Spotify is at 1.8.1.8 and my AVIC-F60DAB is at 1.07. So far Spotify seems to be more stable then before these updates. Sometimes before when I'd hit the play button in Spotify, the Music app whould start to play insted. This does not happen now. And when i navigated the playlists and touching a song in a playlist it whould enter it like a menu entry (showing an empty list instead of playing the song). That too is fixed (hopefully).
