When the mobile phone plays video, the audio and video are not synchronized?

Even the original car wireless CarPlay will have audio delay when watching video. Because video transcoding is more complex than ordinary audio file transcoding, and the processing time is longer.

When pairing, CarPlay does not start or the car prompt device is incompatible/cannot recognize USB

Modify the "delayed start" mode:Enter the dongle setting interface; Find "Delay Start" - change the mode from "Default" to "Mode 1";If this method does not work, please restore the "delayed start" mode to "default".

Cant find Bluetooth or WiFi for dongle?

Please make sure Dongle is powered on and the blue light is on.If only a specific iPhone cant find Bluetooth or WiFi for the dongle, try resetting the network and Bluetooth settings of this iPhone, and then restart the phone.

Audio input or output problem: call rejected or transferred to voicemail/no sound played/microphone inoperative

Please check your phones Bluetooth to see if it is connected to another device. If so, please ignore other automatically connected Bluetooth devices or turn off Bluetooth directly.

Continuous disconnection?

The dongle relies on the WiFi connection with the mobile phone to work. Disconnection is usually caused by wifi interference. Do you have other wifi devices in your car, such as a car camera with wifi function?
