First, if you don't need money, you can download the cracked version online;

Second, for the sake of money, Daotong has upgrade outlets all over the country. You can go to daotong.com-map.com.cn/index.php? Alias = service and service. Action=index Check the upgrade outlets near you and pay the upgrade fee. The cost is about 150-200 yuan.

By the way, even if your original picture is genuine, upgrading will cost money. Daodaotong has not been upgraded for free. After the upgrade, the map and electronic dog data will be updated together. Now all the online downloads and installations are cracked versions, and genuine map manufacturers do not provide online download and upgrade services. I suggest you go to the local upgrade service point to upgrade.
