How can I perform a navigation map update?

AW: In order to keep the map content of your Navigation micro-SD card up to date, it is possible to update map database with a PC tool called “Toolbox” and Naviextras online update portal. On Naviextras you have access to free and pay type updates as well as other add-on’s. The separately available navigation package for the Z-N326 called Z-EMAP50 comes with a 1-year map update subscription, allowing you refresh map content for the period of one year after first (GPS) activation at no cost. Within the given 12 month time frame, TomTom (map provider) would usually release two to three content updates (without guarantee).
For map updates, free content and various add-on’s please visit Naviextras at https://zenec.naviextras.com
