The TomTom go 700 SatNav unit (which now tops the TomTom go line), unveiled at CeBIT, provides hands-free communication via Bluetooth link to your phone, much as your Bluetooth headset would.
If someone is going to interact with others while driving it seems obvious that hands-free Google Glass communication will be safer than texting, as it allows you to keep looking forward at the road.
We have designed it to also deliver stunning voice quality with smartphone and Skype hands-free calls through adaptive communication technologies that can cancel ambient noise and focusing the microphone-array for accurate voice pick-up.
