Cell phones are practically ubiquotous in today's modern society. A natural response to new technology are laws to make that technology safer. Most people use their cell phone as an extension of their physical being, and as such talk and text in the car, which have caused many unnecessary accidents. It is not advisable to talk on the phone while driving at all, but if you must then a Bluetooth handsfree device is the way to go.
Bluetooth handsfree car kits have been around for a while. You would think they would have fairly straightforward features such as a good speakerphone, noise cancellation, caller ID, and overall intelligence, but many of them do not. Thankfully NitroX enters the fray and stands out from the crowd with their X835 handsfree kit.
