Fans of heavy breathing and Star Wars can rejoice - Darth Vader's voice is now available for TomTom in-car GPS devices.

TomTom announced the availability of the Sith lord's voice today, saying it would add a "thrilling dimension" to GPS navigation. Vader's voice instructions include such lines as: "Bear left, to the dark side. Then in 200 yards you have reached your destination. The Force is with you, but you are not a Jedi yet."

His voice commands are priced at AU$17.50 and can be purchased from TomTom's website. They could also be coupled with a free startup screen wallpaper and a Darth Vader driving icon, TomTom said.

TomTom said it would release more Star Wars voices in New Zealand and Australia in the coming months. C-3PO voice commands would be released in June, followed by Yoda in July and Han Solo in August.
