That's for sure! I use the same Humminbird and Garmin on 2 different boats. One boat I'll have the shut off due to starting the engine with the H/B, and one I won't. I know it's a bad connection somewhere, as my Garmin and H/B unit show 2 different voltages on the boat with the start up failure. Too dang cold now to fix it.
