Installed Sygic on my phone from
android-apps-f172/sygic-gps-navigation-2014-maps-t15489-15.html and download all the TTS files from the same thread. The question is how do I enable TTS? If I go to settings, all the TTS voices are marked as "available". If I click one of those, it will download from Sygic's website. I assume if I put the files at the right place, they don't need to be downloaded.
