It looks like TomTom won’t be the only manufacturer offering a GPS app for the iPhone. Navigon recently announced plans to offer two GPS applications for the iPhone this summer. One version of the Navigon app will offer turn by turn directions as well as many of the high-end features found on a portable navigation device such as views of highway signs at complex intersections and lane guidance. The Lite version of the software will offer map views and points of interest but no turn by turn directions. Michael
