Hey @zyrouge I looked into the requirements for this and I got a bit confused on this part:
https://developer.android.com/training/cars/media#onGetRoot
Namely, the part where we have to provide the browser root
i.e. MediaBrowserServiceCompat.BrowserRoot(MY_MEDIA_ROOT_ID, null)

I would assume that we could gather this info from Symphony.kt, but from my understanding there isn't an easy way to share ViewModel data with a service. Am I missing something here? Apologies in advance if this is a dumb question, its been a while since I worked on Android things.

True, ViewModel cannot be easily shared. It seems like it requires only MEDIA_ROOT_ID, so try getting it. I'm not sure how services actually work, so I couldn't help much. If you are working on this, open a draft PR and I'll try to help you out there.
