There's a dynamic interplay between drivers and GPS. When it works, it's their best friend. When it makes an error, it's the stupidest invention in history. How can one improve communication with this vital device? How can the relationship be spiced up?

Might we suggest adding a "Simpsons" character voice skin? Homer's voice has been available for a couple years, but now the options have expanded. Both Marge and Mr. Burns are now available on the TomTom. Maybe not the most soothing voices to talk you out of road rage, but a nice idea for superfans.
