Having the most current maps on your portable navigation device is an important feature, and while all GPS manufacturers release map and software updates, the method and frequency in which you receive them differs by company. For Navigon, it's important to make the entire process as easy as possible for its customers so the company has launched a service called Navigon Fresh, which includes Navigon FreshMaps.
Navigon Fresh is a free application you can download from the company's Web site to your PC and allows you to update and manage content, access software updates for your device, and back up data. To this, you can add Navigon FreshMaps which offers up to 12 map updates over a three-year period. This includes refreshes to the maps and points of interest--all of which are verified by mapmaker Navteq. That said, unlike the Fresh application, FreshMaps requires a one-time fee of $79.99, which is a pretty fair price considering that single updates from other manufacturers cost that much. You can find out more about Navigon Fresh on the Navigon's Web site; the company's GPS devices include the Navigon 2100, Navigon 5100, and Navigon 7100.
