Satnav firm Mio is launching a device with an integrated TV tuner. The Mio Spirit range includes a digital television tuner that is intended to be used 'during breaks in the journey or at their final destination.' However, safety campaigners fear there's little to stop the television being used at the wheel. When the system is first turned on a warning message is displayed, telling the user not to watch television while driving. If this is ignored, a secondary warning message kicks in if the GPS chip detects the vehicle is moving at more than 5mph. But that's it!
