If a cx is asking for map updates they can do so either through the Entune App and then connect to their vehicle using USB or Bluetooth®. A menu will appear on the screen, asking them to choose between updating “NOW” or “LATER.” Select “NOW” and it will take care of all the updates immediately and automatically.
Or they can purchase an SD map card from their local dealership and install it in their USB port's SD card slot, open the "Map Update Toolbox" from the apps folder, then select "Download Latest Content" and it should download within the next few minutes.
The files can also be obtained through Toyota's map database updater through their website to update the SD card.
