Paul, it sounds better than some modifications: -
A friend had Ozzy Osborne as his voice on his TomTom. The commands were something like, "Turn...right...no left!... not right..." etc, etc. You can imagine Ozzy with his dithery approach and wonderful grasp of interjecting curse after curse trying to navigate.
It was so annoying I wanted to throw his TomTom from the window.
