For years I used an older version of igo primo with wav files for speed camera warnings.
Recently I bought a new phone (Android 9) and my old good igo primo doesn't work anymore.
So now after a lot of reading I managed to gather ..
1. iGO Basar 9.18.27.736574 - 13.June 2018
It works ok
2. Universal unisex TTS and engines v.1.x
Greek lang works ok
3. Vocalizer_e_tts_1.0.2.3t + Greek melina voice
It works ok

but I can't get the speedcameras warnings work in my phone !!!
I've tried many different sys.txt with no success.
How can I make it work ? Or it just can't be done ?
