Rider2 Navcore9.5xx - No TTS

Using Downunder's navcore installer I have my New (to me) Rider 2 updated to navcore 9.500.

I read that these modified navcores will free up some RAM permit the useof at least VocalizerTTS if not LoquendoTTS.

I have the vocalizertts (as well as loquendotts, just to try) in the root of the SD card but the voices never appear in the list of installed voices.

Not a huge deal and I'm happy to have some of the newer features available (winding roads, etc) but if there is a way to get some basic TTS support I'd be glad to have it.

Note: Maps installed support TTS.

No TTS is not working.

So no combination of navcore or map will ever get the TTS working?

To my knowledge not for a Rider.
