Add 'Simpsons' voices to your TomTom GPS

If you own a TomTom GPS and you're a "Simpsons" fan, you're in for a treat.

For the past couples years, you had the option of putting the voice of Homer Simpson into your nav system. Now, TomTom has landed two more "Simpsons" cast members: Julie Kavner and Harry Shearer, who lend their considerable vocal talents to Marge Simpson and Mr. Burns, respectively.

Excellent.

These "Voice Skins," which sell for $12.95 apiece, take the place of the stock voices contained in your TomTom. (Actually, you can switch back and forth between voices as desired.) The only downside is that you lose out on street names: Instead of hearing, say, "Turn left on Maple Road," you'll hear, "Take the next left."

Of course, when you're hearing it from Homer, Marge, or C. Montgomery Burns, who cares? I've had the Homer voice since it was first available, and to this day it still makes me smile. It's especially great when I have passengers, who always get a chuckle out of it.

Want to know what you're getting, voice-wise? Click the preview clips for any of the characters.

Curiously, TomTom doesn't mention anywhere that Dan Castellaneta et al are responsible for the voice-overs, but there's no question these are the real deal. (I'll fight anyone who thinks otherwise.)

To install these or any other TomTom celebrity voices (the Mr. T one is particularly hilarious), you'll need TomTom's desktop software, your GPS, and the USB cable that came with it.

You can load voices on pretty much every TomTom GPS made in the last few years. Personally, if I was shopping for a new nav system, I'd choose a TomTom over a Garmin or Magellan solely so I could listen to Mr. Burns tell me where to go.

Indeed, if you're tired of hearing that same old robotic GPS voice, this is a great way to liven up your trips.
