After connecting the device, GPS becomes laggy. How can this be resolved?

1. Press and hold the hidden button on the device for 15 seconds to reset it and restore the device settings to factory defaults, so as to avoid location delays caused by abnormal configurations.

2. Make sure the phone's location service is turned on and the navigation app has been granted location permission; also enable the WLAN scanning feature, which can improve location accuracy.

3. After completing the above settings, reconnect the device and test again.

Additional note: Adapter-type products do not come with a built-in positioning function; navigation positioning relies on the phone's GPS and other location systems.
