Anyone has luck to install TTS successfully for TomTom 7.20 on a PDA (WM6)?

[bittersmile]

I have put the LoquendoTTS folder (contains all necessary 'Susan' files) under the root of SD card, but I cannot find the option (Susan, Computer) in TomTom "Voice Preferences". Do I need put anything about "Susan" under the voices folder?

I also put a lot of voices (chk and vif) under the voices folder, but it seems not all voices are listed in the "Voice Preferences". What might be the problem?

Thanks a lot!
