If you replaced your in-car music player and dedicated GPS nav kit with a smartphone, here’s something that should help keep your hands on the wheel: TomTom has launched a pair of hands-free car kits for smartphones that promises to enhance voice call quality while driving.

It’s totally unnecessary, but unnecessarily awesome nonetheless. TomTom has teamed up with Lucasfilm to give you the (again, awesome) option to replace your TomTom navigator’s default “voice” with Star Wars voices, including Darth Vader, Yoda, Han Solo, and C-3PO.

TomTom has recently come out with a new international edition of the TomTom XXL 540S navigator called the World Traveler Edition. The new model simply adds maps for Europe (as well as maps for US and Canada) for people who routinely travel across the pond, while the existing 540S comes with North American maps. Aside

TomTom has just announced the XL 340S LIVE, a mid-range GPS kit that updates map and travel info live via AT&T’s mobile cellular networks. The XL 340S LIVE sports a 4.3-inch full color touchscreen and an interface that shows the usual mapping, traffic info and weather forecasts, but adds Google Local Search and gas prices

TomTom has finally released their SatNav app for the iPhone. Available in four regions, the app will cost around US$80 in Australia, US$95 in New Zealand, US$140 in Western Europe, and $100 in US and Canada (with US coverage including Alaska, Hawaii and Puerto Rico).
