For vehicles with weak USB power output (e.g., certain Nissan, Isuzu, Toyota, Lexus, and Volkswagen models), use the included Y-shaped power cable and connect it to a cigarette lighter socket or a high-power USB port.

● Possible power cable issue

If the AD5 still does not power on, the supplied power cable may be defective.

Please contact your dealer or ATOTO official customer support to request a replacement cable.

Issue 2：

Original car head unit cannot recognize AD5 system even when properly connected and powered

Reason & Solution

●Incorrect connection mode: Ensure AD5 is in the correct mode (CarPlay or Android Auto) according to your head unit. Press and hold the "CP/AA" pinhole for 2–5 seconds to switch between CarPlay and Android Auto.

●Compatibility limitation: Certain car models or head units may not fully support external Android system overlay. Check AD5 compatibility list.
