I am installing a SmartPilot X-5R that I bought new several years ago and was not able to install at the time. I have connected a Lowrance HDS8 chartplotter using the NMEA 0183 connection as I want to use the compass data from the Lowrance. I did not connect the fluxgate compass. When I power both units up, I do not get compass data on the display (it just displays dashes). I connected a LED across the output from the Lowrance and it is sending a signal. Any thoughts?
