Here are some tips for the connection:
1. Please note that before using Android phone to connect MirrorCast, make sure you have completely exited Android Auto.
If your phone and stereo have used Android Auto before, then even if you exit the AndroidAuto interface in the stereo, AndroidAuto will still be on standby in the background of the stereo system.
At this time, you need to pause the AndroidAuto link in AndroidAuto on your phone.
2. Then enter the PhoneLink settings of the stereo and turn on the MirrorLink button under Android, which contains detailed MirrorCast connection instructions.
3. Download and install the MirrorCast app to your phone through the QR code above, and then you can perform MirrorCast through the hotspot settings. Please try it.
