Navigation software, whether the stars can be found is related to port settings; The speed of searching stars is related to the baud rate setting.

1. If you don't know the port of your navigator, you can search Baidu, extract the "GPS port and baud rate detection tool" on your computer, copy it to a blank SD card, and insert the navigator to display the port, baud rate and screen resolution of the navigator.

2. Then use the navigation port modification tool to modify the port and baud rate of the navigation software to be consistent with the navigator, and it will be OK.

I hope I can help you, and I hope to adopt it!
