Not literally, of course. Instead, that $12.95 will buy you the voice of Darth Vader on your TomTom GPS device, according to Consumer Reports. The legendary villain is the first "Star Wars" character -- of a planned four, including C-3PO (June), Yoda (July) and Han Solo (August) -- to get a spot on the company's roster of fictional characters giving you real-time driving directions. The service, available only on TomTom software version 5.0 or higher, also includes free "Star Wars" downloads with startup screens, icons and sound effects.
