perodimi Posted December 27, 2008 Report Share Posted December 27, 2008 Happy Holidays All, The wife bought me a Humminbird 747C Fishfinder for Christmas and it says you can input your handheld GPS to it. I have a Lowrance Ifinder H20C but the only NMEA cable available is a 9 pin PC connection. Does anybody know how to interconnect these or if it is at all possible so the Humminbird can display GPS info? BPS wasn't much help so I was wondering whether to exchange it for a different unit that is compatable. Thanks, Peter Link to comment Share on other sites More sharing options...
forrest Posted December 27, 2008 Report Share Posted December 27, 2008 (edited) alright...I was a bit naughty...I have many days to be nice. Contact Humminbird, their website has a GPS adapter cable Contact Lowrance, they should have the same or you can make your own. NMEA is a standard communication protocol. My Garmin unit has 4 connectors on the back NMEA IN +, NMEA -, NMEA out+ and NMEA out-. The unit is running NMEA 0183 Humminbird can tell you what the other wires you have are for. the unit Humminbird sells for hooking up to the unit is the GR4 GPS Receiver, its about $100. forrest Edited December 27, 2008 by forrest Link to comment Share on other sites More sharing options...
