How to change Carson's channel resolution to Kay LiDE, which is not supported?
The port, baud rate and machine feature code of each machine may be different.

It's very simple: Baidu downloads a "GPS port and baud rate detection tool", decompresses it on the computer, copies it to a blank SD card, inserts it into the navigation card slot of the navigator, opens it, and presses the navigation key to start it, then the port, baud rate and screen resolution of the navigator can be displayed.

Then, download and install the Khalid version with the same resolution as your navigator.
