Lowrance – Networked temperature sensor

I have an X-28 and 520 that are networked and the temperature probe is also on the network. If you go to the digital data screen, there is a water temperature graph but there is no source because it’s looking for the normal temp sensor input, not the networked one. I can’t figure out how to make it read the networked temp sensor. Going into the customize screen (or whatever it’s called) menu will let you select everything but that graph. I know it’s not a big deal, but thought I’d throw it out there for ideas.

Anything connected to the NMEA backbone shows up under the NMEA devices. Look for the temperature probe there.

Yep, but it won’t even allow me to verify or change the settings of this temperature graph to select anything. Wondering if I’m missing something obvious or what the deal is with that.
