I'm afraid I'm in the same boat as lot of other people here.
I got no problem getting the Android part working. VocalizerEX installed and set as default TTS engine in Andoid. VocalizerEx recognizes my language pack and plays the test just fine.
But somehow i can't activate TTS in my [Only registered and activated users can see links. ]. TTS language pack downloaded from [Only registered and activated users can see links. ]. From what I've read/heard iGO is very picky with TTS packs so i tried multiple files besides the Dutch like US English and UK English... none of them seems to be accepted by iGO as in not any TTS voice is selectable in iGO. I deleted the save folder.. i even reinstalled iGO completely.. same result in iGO all the time, not a single TTS voice is selectable.
