I am using iGO PAL 9.18.27.719974 - 15. November 2017 with VocalizerEX, everything is working but I can't get the TTS to work in my android car unit (Android 6).
I have the exact same thing on my phone (Android 7) and everything is working including TTS. Can someone figure out what's wrong and help me fix it?

I have tried many other voice engines for my car gps and it work fine with igo primo but not igo nextgen. Can someone please help me? Many thanks.
