Mobile phone sat-nav to overtake dedicated devices

Navigation using mobile phones is going to dominate the GPS sat nav market, according to a new report from Telematics Research Group. Although around 30 million personal navigation devices were sold worldwide in 2007, handset manufacturers also sold 20 million navigation-enabled phones. TRG reckons that navigation-enabled phone sales will overtake dedicated navigation device sales in 2009 - and will lead to a total of 500 million units being sold in 2015. [PDF press release]
