For anyone wondering why you car stereo doesn't work with Spotify via Bluetooth, the latest patch broke it. Spotify took away a feature I believe called Spotify Link (maybe Connect) that allowed aftermarket stereos to use the integrated app. Unfortunately it's gonna stay like this for awhile... Spotify most likely isn't gonna implement this feature back as I have contacted Spotify with no help. I use a pioneer and they told me they are trying to work with Spotify to get something working.
