However, if you purchase the latest SD map from the dealer, the update validity period will be extended for 2 years, and you can continue to use the disc with the latest nationwide map update. Please refer to the instruction manual for the map update procedure. ☆ You can only select "3 prefectures" at a time for the navigation update, so you will need to repeat this several times to complete the update for all prefectures. We are waiting for your questions. Thank you.
