Mine says no sources also but it does shows (KMC5) and won't work until I change the instance in device list. I have to change the instance every single time I turn either the radio or the Simrad off and back on just to get it to work properly.
Just had my new simrad evo 12 installed. When I turn it off, it turns off my Fusion Stereo (RA770). This is being done through the NEMA2000 connection. Where is the simrad setting to configure to not shut down the Fusion stereo automatically?
