Well guys I managed to find solution and it seems everything working fine.
[Please Register or Login to download file] 1. Downloaded GPSScan Debug and ResInfo
2. Started GPSScan to get port and baud which is port=2 baud=57600
3. Added port=2 baud=57600 to sys.txt and disconnected from PC
4. Turned on device, started windows exploler then clicked on ResInfo and disabled Becker software.
5. Then started Primo and it found GPS receiver straight away.
Now just need to find out how to disable becker software permanently.
