I just replaced my Lowrance HDS-12 GEN2 Touch on my 2014 Puma FTD with a new Humminbird Solix. Now the Smartcraft (Beede) rpm gauge will not read GPS mph. When removing the Lowrance unit, I noticed the yellow wire from the unit was connected to the orange wire from the Smartcraft gauge and the ground (shield) wire from the Lowrance was connected to the ground wire. Is there a way for me to connect the Solix to the Smartcraft gauge so it will read GPS mph? I purchased a mercury gateway and installed it so the Smartcraft information is displayed on my Solix. However, that did not help with the MPH info on the Smartcraft gauge. This is apparently because the gauge needs NMEA 0183 input and not NMEA 2000 input.
I have been messing with this thing for a couple weeks. If anyone can help me, I would really appreciate it!
