TomTom portable navigation devices (PNDs) have been known for the ability to customize route guidance with downloadable voices, but this latest addition to the voice catalog takes the concept to a galaxy far, far away. TomTom has introduced the first of four scheduled officially licensed Star Wars voices: Darth Vader.

Available for $12.95, the authentic-sounding voice provides guidance as only a Sith Lord can, complete with references to the Dark Side. To complete the navigator upgrade, there are free Star Wars downloads with start-up screens, sound effects, and car icons.

The next character coming is C-3PO, with Yoda expected to follow in July and Han Solo in August. No word on offering Chewbacca. We imagine that the Yoda voice could be a challenge to interpret, given the big-eared Jedi's tendency to transpose words.
