Any reason why I shouldn't be able to adjust water temp setting on my Helix while in the garage?
Friend came over with his expensive temp "gun" to help me "calibrate" my temp gauges. Idea was to read the temp at the probe on my XM 9 20 MSI T xdcr and then adjust the temp on my Helix 10 SI Mega Chirp GPS G2N unit on the console up or down to match. I was doing this while on the 2D sonar screen. Then once back on the water with the trolling motor down I would set the temp on my bow Helix DI unit to match the console reading. I did this once awhile back when I was running v1.84 and it worked fine. Watched the temp on the screen move up as I adjusted it up 3.5 degrees.
But today, with v1.90 it flat did not work. Unit read 52.3 and the temp gun read 48.0. Adjusting the temp gauge down on the unit did not change the temp reading on the screen of the SI unit. Adjusting it up OR down did not change a thing. Rebooted the unit and tried again with same result. Is this another glitch in v1.90 or am I doing something wrong?
