With the continued proliferation of in-vehicle navigation GPS systems, portable navigation devices (PNDs) and mobile phone navigational functionality, consumers are being offered ever more choice in the way they experience navigation and location-based information. In 2009, roughly half of all people in mature markets such as US, UK, France and Germany reported using a GPS navigation system – which is approximately double the number reported in 2006.
According to Jeff Mize, executive vice president of Navteq sales, “As navigation and location based services become increasingly mainstream, there continues to be a need for a wide range of GPS navigation offerings.”
