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” via the Naviextras online update portal. On Naviextras you have access to free and pay type updates as well as other add-on’s. The navigation package for the Z-E3756 comes with a 3-year map update subscription included, allowing you to update the map content for the period of three years after first (GPS) activation at no cost. Within the given 12 month time frame, TomTom (map provider) usually releases two to three content updates (3rd party offer, without guarantee for update cadence).
Navigation software updates, Add-On content und map updates are available here: https://zenec.naviextras.com
Disclaimer: The card update subscription duration can only be guaranteed in its entirety in conjunction with a new device which is put into service together with a new navigation card. For used devices with navigation packages purchased later, limitations apply because the date of the first use of device is crucial. Naviextras places a time stamp point on the device once first sat connection is established.
