The strange thing about the GPS is that when I turn it off in the config panel and then enter the C-Map it seems to run as it should with the GPS picking up a signal indicated by flashing LED light on it and the boat icon on the map where it should be and all of the other long/lat ect rolling over as if active. So dose the map programme run the GPS even after I have disabled it? and is this normal?
From what I can see the BU-353 is a USB GPS capable of outputting NMEA. I'm guessing it came with some driver software
that allowed it to install a COM port on your PC. Check in Device Manager double clicking on "Ports (COM & LPT)". In the listing should be an entry corresponding to your GPS, with a COM port number.
Once installed correctly you don't need any other software
to make the GPS work. Just plug
it in & then configure C-MAP to connect with the COM port you found to receive GPS NMEA.
If you have trouble configuring the correct port within the C-MAP application, I believe there is a configuration file in the installation
called CMAPECS which can be configured manually with a text editor.
