I know you can add different voices to some gps units but I don't see a way to on this model.

Internet search turned up with nothing as well, I also did the search while at work and could not really dig into the search.

So I thought I would ask here....any ideas?

Have you tried beating it with a stapler?

yeah all it did was moan and call me daddy...but didn't change the voice at all...kinda creepy actually
