Cartel’s CT-2000 Bluetooth-enabled handset for your vehicle is a permanently installed device that will be connected to your audio system, allowing you to route your cellphone calls to it so that you can concentrate on driving with both hands on the wheel. Sounds more like a permanent Bluetooth hands-free kit than anything else, and the design folks behind the CT-2000 must have just stepped out from a time machine in the 1980s.
