After upgrading to 6.0, my car keeps saying "cannot view content of selected device.

[AC Question]

So basically before i upgraded my galaxy note 4 to 6.0 i could use the dial in my car to change and scroll through my albums/artist. Now after the upgrade i can only change and go through songs on my phone. I keep getting a "cannot view content of this device" error. The one thing i did notice is that on 5.1 i was not using google play music to play songs when connected to my car. Bluetooth is working fine, i just want to be able to select my albums again from my car. I think it is because im not using the same media player as 5.1 did which allowed me to access all my music.
