After softwware update

[Copefishin]

I have 4 axiom 9 mfd. (2) at the console and (2) at the bow. I have one as the master and two of the units networked to it -

After the latest 3.8.97- I had to do a factory reset because the unit wouldn’t recognize transducer. After getting that figured out. I’m not able to read the water temp at the master unit. I’m getting -.-

Second issue- one that I hadn’t noticed before. I’m losing bottom on plane at higher speeds. Trolling speeds are ok most of the time. I have a p-72 and rv-100.

Do I need to assign where to get the water temp from ? Data source? Reinstall software?

Thanks in advance
