Can my iGPS unit use an external antenna?
Yes! By placing an LGC-2000 or LGC-3000 on the NMEA 2000 network with the iGPS unit. • Once the LGC-2000/3000 is connected to the network and the network is powered, press Menu, select NMEA 2000, then Bus Setup. • Select the LGC-2000/3000 on the list. • Highlight Set Active and press ENT to place a check mark in the box. • This process makes the LGC-2000/3000 active and disables the internal GPS receiver.
