When I start ABRP (on an AppliePie box with Android9), it opens Google Speech services in Google Play, which are installed already. There's no speech output in ABRP.
Samuel presented a workaround for a similar issue in this thread: abrp.upvoty.com/b/report-a-bug/abrp-not-starting-on-android-auto-on-kyebriq

Same here. Using ABRP on the Apple Pie Mini ux999 ... I have the problem that I cannot hear any navigation voice from ABRP. It seems to be caused by some issue with Google Speech Services. They are installed but it seems not recognized. Every time I boot the ABRP app, it switches to the play store and shows me the Google Speech app.
Tapping back to ABRP, I can use it but without hearing the commands.
