Who Me Too'd this topic

In my 2011 Volvo XC60, I have my iPhone playing Spotify via USB connection. All the song meta data shows up fine on the screen. When using the steering wheel controls, I am unable to use the back button to move back a song (It actually skips forward). The forward button skips forward as expected. When I hold down the back button, I can rewind the song, and when I hold down the forward button it moves the song forward. I have confirmed this is a Spotify specific issue, as other apps work correctly with the back button as previous song. Any help will be appreciated and I can provide any additional information that is requested. Thanks!
