Is no way to use a third party music player in Android auto??? I think it is time for Google and Samsung to implement or leave us using other music apps.
Supposedly you can get the Samsung music app to show up by enabling developer mode in Android Auto and selecting enable unknown sources. To enable developer options in the Android Auto app settings, scroll to the "About" section, and tap the "Version" entry 10 times until a message appears confirming it is on. Afterward, select "Developer settings" from the three-dot menu in the top right.
