Ah, OK. What you were probably doing in CM6 was running Google navigation without
text to speech, which means your navigation was using pre-recorded generic messages like "turn left" instead of saying street names out loud like "turn left on to main street". The pre-recorded messages were of a person actually saying it so it sounds good. Pico TTS is tolerable but definitely not human sounding.
Just to clarify, Pico TSS had to be manually downloaded in CM6 but is now included in CM7, hence why you have it.
If you have S-OFF you can probably try to uninstall it manually. I'm not sure if it's enough to just remove it from the app folder or if you need to do anything else, but it should be possible. If you don't have S-OFF you can reflash a modified CM7 zip with Pico removed.
Alternatively, like tedkunich said, you can get another text to speech (though there aren't any good ones that are free) with a better sounding voice.
