I have read the instruction and went over them several times, even watched the garmin guru on YouTube it’s assembled according to the manual, checked, checked and rechecked. On my sonar setup on the screen it has 3 options auto, forward, and perspective. If I turn it on the other side every thing works fine. But the trolling motor cable is in a bind when it’s fully down. I’m afraid it’s going to break the cable. So I changed it auto, if that don’t work I will call chuck and we will calibrate it.
