To update maps on a Nextar GPS, visit the Nextar website, download the Naviextras Toolbox, connect the device, and find the correct update. The final steps are to checkout in the shopping cart and update the device.
The Nextar company recommends downloading the updates from the Nextar website through the Naviextras Toolbox, but it is also possible to do this through the website instead of through the software. Connect the Nextar GPS to a computer with a USB cable, and log in with a username and password, or create an account.
When opening the Toolbox software, the Catalog button helps with navigation, and by pressing it, a list of updates and maps appear. All of these maps and updates are compatible with the device, and by clicking the shopping cart icon, the update is ready to buy. Some of the updates shown are free updates, while others have a price listing.
When ready to purchase, hit the Checkout button, and pay for any purchases with a credit card. When payment is complete, the updates are available in the Toolbox navigation bar. All free updates and purchases are here, and installation can begin. Before installing the updates, however, it is best to create a backup of the advice just in case something happens.
