The devices will go on display at the 
            Consumer Electronics Show in Las Vegas this week.
             
            
            However, motoring organisations have 
            warned the so-called “infotainment” systems will distract drivers 
            and increase the risk of accidents.
             
            
            Duncan Vernon, from the road safety team 
            at the Royal Society for the Prevention of Accidents, acknowledged 
            that sat-nav systems could help motorists, but warned that too much 
            gadgetry was dangerous.
             
            
            “All drivers have to navigate when they 
            are behind the wheel, and technology such as sat-navs can help 
            drivers do this when used appropriately,” the Scotsman quoted Vernon 
            as saying.
             
            
            “But there is a serious potential for 
            distraction, and related crashes, resulting from visual display 
            entertainment systems unrelated to and unnecessary for driving. Most 
            of us would be shocked if we saw a driver reading an encyclopaedia 
            or texting behind the wheel, and rightly so. When behind the wheel, 
            a driver’s primary task is to drive,” Vernon added.
             
            
            Edmund King, AA president, said: “We must 
            accept that technology is evolving and will not go away. But in 
            general terms we think that the internet should be reserved for the 
            cyber-highway rather than cause distractions for drivers on the real 
            highway.” 
             
            
            Neil Greig, director of policy and 
            research for the Institute of Advanced Motoring, said: “The impact 
            of these devices on driving standards has not been sufficiently 
            examined. Therefore it must be a basic requirement that the new 
            interactive technology only works when cars are stationary.”
