“… turn left after 300 metres” commands a friendly voice to the driver. Unfortunately, you can no longer turn left as the street has been blocked off since the navigation system was purchased. Those who would like to avoid such frustrating moments and also would like to drive along the newly opened bypasses must depend on current map materials. Starting at the end of September, Hama’s elaborate distribution channels will provide four upgrade versions for PNAs (Personal Navigation Assistant), thus allowing you to upgrade to the latest Navigon software MobileNavigator 6. Preinstalled on the SD memory cards, the upgrades are suitable for most mobile devices.
