First off, many thanks to xpsworm for starting this thread.

I have spent 2 days playing with different configurations and settings and was about ready to give up on TTS but with the help from several posts in this thread I have iGO8 installed and working on Mighty Rom 02.04.2010.

I am using the mortscript posted earlier (the one that runs "CleanRam") with the CleanRam settings as suggested. The script closes HTC Sense perfectly, runs CleanRam (usually with a ram savings of between 11 and 14MB) then runs IGO8 with working TSS! Then when I exit iGO8 it restarts HTC Sence and I'm back to normal.
NOTE: I also use Gyrator2 and it keeps TTS from working so I added it to the CleanRam list of programs to kill, then I added a line in the mortscript to restart it on exiting iGO8.

BONUS: Another thing I discovered that is an added bonus, I have a Bluetooth Stereo in my truck and if I switch to Bluetooth Audio on my stereo the voice comes through my speakers perfectly.

The only thing that would make this set up better is if I could listen to music and have the TTS voice over-ride the music when it is needed like it does when I receive a call. The way it is set up now I can only do one, either Navigation or Music.

Again, thanks to all who contributed information to this thread, it has been a great help.
