D'oh! Homer isn't the only Simpsons character who can tell you when the next left turn you'll need to make is. TomTom has just landed a new agreement that brings the blue-headed wife Marge, as well as Mr. Burns into the picture. It isn't talked about as much since the novelty wore off, but celebrity voice guidance is one of TomTom's most distinct differentiating factors over the competition. Personally, we pity the fool who doesn't have Mr. T or someone equally as iconic giving them their turn-by-turn, sattlite-assisted directions.
