The ability to search in Roon ARC is missing from the Android Auto implementation. This is available in every other music player I have used (Spotify, Qobuz, Symphonium, Plexamp) on Android Auto. The implementation is generally a floating search button. If the vehicle is moving, search is restricted to voice input only. Otherwise, a keyboard is available.
I do not see a current Feature Suggestion for this. I have found other forum posts about it, and the one workaround mentioned is to use Google Assistant to “Play X using Roon ARC”. I tested this briefly and was unable to get it to work before my Android Auto was “upgraded” to Gemini. Gemini happily complies with my request (responding with a “Playing Dark Side of the Moon using Roon ARC”), but nothing actually happens.
Here’s a recording of how Qobuz implements this, obviously parked and not driving. 
Good afternoon.
Any plans to improve search in Android Auto (for ARC)?
At present, and since the beginning, I think, there’s been no search function in ARC’s Android Auto interface whatsoever.
Other music apps have it, namely Qobuz, but not ARC.
Also the support for Gemini is very hit and miss. I must say “play x from y artist on Roon Arc”, even if I’m on ARC, and most of the times, it fails…
This, added to fact that only a subset of one’s library is available on Android Auto, makes using ARC trought Android Auto, a bad experience, IMHO…
Thanks in advance.
I’ve merged your post with the existing thread for this suggestion.
If this feature suggestion is important to you, please vote for it by using the Vote button at the top of the thread. Thank you.
Thanks.
I find it unexplainable, though, that one has to vote for a feature as simple as “search” on a car.
Oh well…
