Is there a map update available for my nav-u™ portable navigation device?

    Currently there is no map update available for these models. However, there is a firmware update available for your nav-u unit. Although the firmware update does not provide additional map data, it may improve the route quality of your map in certain situations. The firmware update is available from the Sony® Support Web Site.
