I think they were talking more of a separate switch, from the battery, that you could hit, and power the GPS/EFIS only, and then when that was done, going onto engine start. I am no electrical genius, which is why I was asking if a switch over like this is possible. In other words, hit a switch, program, and then go to engine start without losing power to the GPS/EFIS, forcing a reboot.
