(III) Before you run this device, please do correct setttings of the map software in your Mobile phone. We take Careland  map software as a example,
you need to config one file in advance , as follows,
COMMPORT=COM6:
BAUDRATE=9600
Please note that there is Colon behind the number 6. some software does not a file to setting . By the way, most BAUDRATE rate port is 4800. You can try 4800 if 9600 not work your GPS.
Just note that the bluetooth will send indications command when you run the map procedure every time, so GPS detecting completed automatically.
In a word , 3 points you need to take care for settings:
(1)Window 6.0 bluetooth setting,
(2)Win6.0 external GPS setting.
