Hmm I noticed something maybe it is just the case with my device. When using TTS, after I added all the necessary things I noticed that my gift was a little bit slower. When I did simulation and by pressing next next I noticed it is bit more sluggish takes time to process request. I did my restore without tts and everything works perfectly. I am not sure if this is a isolated case but this is what happened to me. Anyway for me TTS is not so important, I need good routing, fast response and simple graphics.

Have a nice trip.
