Why no satellite signal? How to setup related iGO navi software

Some customer installed our igo map software, but it is not any satellite signal,similar interface as below;

It is because it can not autodetect the related parameters of gps device.

Now you just change these parameters as below steps;

1.check port / baud in the original map software;

2.open sys.txt in your map software, change these 2 parameters;

If port = 1 in the original gps device, port=”1″
If baud= 9600 in the original gps device, baud=”auto”

Then, inset SD card into GPS map slot, restart gps device to run igo map software.
