免费升级e-Road 地图时需要记住很多事项。
您首先要检查导航仪的型号和版本，例如标准屏LH900S或LH900N升级版。您需要删除原始SD 卡上的kld 文件。解压下载的地图软件，将E-line通用屏KLD文件中的KLD文件夹复制到SD卡根目录下。
对于EV5这样的高清屏，操作类似，但文件名不同：E-Road HD KLD。
另外，请检查免费升级服务期限通常为2年。
请访问官方网站检查您的地图版本是否是最新的。
If your memory card doesn't have enough memory when you upgrade, you'll have to pay for an additional memory card and have Affordable Channel update it, or buy a memory card and send it there and cover the round-trip shipping costs.
您可以登录网站，进入您所购买的导航仪的下载区，更新最新的地图数据。
When inserting a map card into the navigator for upgrade, make sure the navigator's power supply is in a stable environment to avoid interruption, and back up important data in advance to prevent loss.
If the update fails, you can send your Navigator back to the Affordable Channel for a free update and you only have to pay for round-trip shipping.
