         <source>When navigation has a destination, openpilot will input the map information into the model. This generally improves behavior and allows openpilot to keep left or right appropriately at forks/exits and take turns. Lane change behavior is unchanged and still activated by the driver. This is an alpha quality feature; mistakes should be expected.</source>

+        <translation>當導航有設定目的地時，openpilot 將會把地圖導航信息輸入模型。這通常會改善 openpilot 的行駛路徑使它能夠在分歧處/出口適當地靠左或靠右，並進行轉彎。車道變換行為保持不變，仍由駕駛員手動執行。這是一個 Alpha 版本的功能，請保持心理準備隨時有可能會出現錯誤。</translation>
