Make sure on your HDS that the NEMA 0183 setting is on. The gps sends its signal to the gauge via the single 22 gauge wire. The graph has to be set to share that signal. Assuming you havent messed with the wires, read the following link (even if you messed with the wires, there is an explanation for those too).http://continuouswave.com/ubb/Forum6/HTML/003033.htmlI believe the only “sentences” the gauge needs are:GLLVTG(lat/lon and ground speed).Last edited by catmantwo on May 23rd, 2015, 11:58 pm, edited 2 times in total.Your Signature …
