I shied away from the TTS because I found the original Mio software to be laggy and unresponsive, and didn't want to do anything to slow this down. I also read that whilst most 32Mb devices could handle TTS the 64Mb+ devices were recommended.

However, given your recommendation I'll give it a couple of weeks to make sure that it's running smoothly and put it on. I'll look into the other features as well, but they don't seem to particularly stand out. The main thing is that the map can be updated easily now.

I have one myself, you can throw everything at it and it doesn't complain, or slow down.

use the tts I link to in the guide.
