When using GT8D, if your iPhone is simultaneously connected to other Bluetooth devices (such as the car’s factory Bluetooth system or wireless earphones), the audio may not be output from the AI Box.

In this case, please go to the Bluetooth settings on your iPhone and:

• “Forget” or remove other Bluetooth devices
  
• Keep only the Bluetooth connection to GT8D (AIBOX)

This usually resolves the issue.

The GT8D may still be connected to a Bluetooth device, which can cause the audio to be routed incorrectly.

Please try the following steps:

1. Open Settings → Connected devices (or Bluetooth settings) on the GT8D
   
2. Check whether a Bluetooth device such as “AIBOX” is shown as connected
   
3. If it is connected, select it and choose Remove, Forget, or Ignore
   

In most cases, this will restore normal audio output.

The zoom function depends on the design of the map application. Many map apps are designed to zoom using multi-touch gestures (pinch to zoom). However, most car infotainment systems and the CarPlay protocol only support single-touch input, which limits this function.

Some apps include on-screen zoom buttons that allow you to zoom in or out (for example, Amap car version), while others like Google Maps may not provide this option.
