Hi, just installed Waze and it's great (I reported a speed trap in my first 15 minutes). However, I've downloaded a text-to-speech engine (IVONA) that is much better than Android's robot and the Waze voice. I'd really like to use my chosen/default TTS engine, not Waze's built in one.

I'm an advanced user, though I've been avoiding rooting my phone so far. Motorola Photon 4G, stock, GO Launcher EX.
