Manitoba | What the suggestions are is for cutting the power from the combine batteries to the separate gps battery, doing this will eliminate any potential reduction of power to the gps unit when the reverser draws heavily, then once done reversing the connection is reestablished to keep the gps battery topped up
Normally the gps unit doesn’t turn off when the reverser is engaged, but continual low or poor voltage (my hunch or theory) causes all kinds of weird stuff. I had a situation with a master cab solenoid that was going and Dad was ready to throw the gps out he was so frustrated.
I would set it for him and all would be well, then within half hour it would be driving anywhere but the a-b line. Power still lit a test light but when I eventually got a multimeter on it the voltage was erratic and never a full 12 volt
After that I always run separate cable all the way to batteries, but maybe in this case that’s not good enough.
