The days of supremacy for the Portable Navigation Device (PND) in the global navigation market are coming to an end with the rise in worldwide usage of GPS-equipped smart phones in the coming years, according to iSuppli Corp. After several years of strong sales growth, PNDs will continue to lead the navigation market in 2009, with 114 million sets to be in use by the end of the year, compared to 57.8 million smart phones. However, by 2014, usage of navigation-enabled smart-phones will rise to 305 million units, exceeding the 128 million PNDs that will be around by then. The figure presents iSuppli’s forecast of global usage of PNDs and navigation-enabled smart phones. “Previously, smart phones were not seen as a threat to the dominance of PNDs due to mobile handsets’ poor battery life, unclear pricing structures and inferior interface,” said Danny Kim, global Location-Based Service analyst for iSuppli. “However, as smart-phone design moves forward, many of these issues have been or will be resolved, leading to increased market share for navigation applications on smart phones.” iSuppli predicts that in 2011, nearly 100% of all smart phones shipped will integrate GPS functionality.
