Received a message with too low etc version.

If you receive the message "ETC version is too low", it is usually because your ETC device version is too old and needs to be upgraded. In China, many banks and operators provide ETC equipment. If you receive this message, you can contact your ETC service provider to learn about the specific process and requirements of equipment upgrade. Generally speaking, ETC equipment can be upgraded online or offline. If your ETC device supports online upgrade, you can log in to the bank or operator's official website or APP and follow the prompts to upgrade. If your ETC device does not support online upgrade, you can go to the relevant service point to upgrade.
