TomTom has finally added a couple more Simpsons characters for its Voice Skin GPS systems. Homer has been available for a couple of years now, but they’ve also added Marge Simpson and Mr. Burns. Expect to hear Marge’s raspy voice as she guides you around town, while Mr. Burn will provide nothing but constant insults with him guiding you. Both voice packs are now available from TomTom’s site for $13 each. Here’s hoping TomTom adds more Simpson characters like Bart, Lisa and other Springfield favorites.
