Taking navigation to spy levels is not something that makes us marvel. The LiveWire NavGenius makes a good spying and eavesdropping tool for those who’re a bit too eager to follow the whereabouts of someone. Besides being a fully functional GPS satellite navigation system, it also packs SMS and email. Other features included are a touch screen display, 2GB internal memory and an in-built speaker. If the vehicle it is on exceeds speed limits or gets too rash on the road, a silent SMS alert can be sent.

Youngsters are bound to fall prey to the cunning device’s stealth notification system. That’s if their guardians are willing to pay $600 for the tracker.
