Android Auto and TTS

I read the docs here:

It says that I need to install:

  • Google App
  • Google Maps
  • Google Speech Services (formerly Google TTS)

Now, I don’t plan to use Google Maps but OsmAnd or something else. It does say I can install sub versions. Has anyone tried?

If I install the stub for TTS/GSS, what else can I install to provide that functionality?

From a source here (some of the AA threads) I installed espeak, and on top of it SherpaTTS, then voice works. Mind you, I don’t have osmand, but comap and here we go
