Just bought a new battery because the old one was clearly dead, but I noticed that my nav unit in the trunk just randomly turns on even if the car isn't turning on. Can the nav unit be a source of power drain?

NAV unit always begins to boot up when you unlock the car or open a door (in this case your trunk was open to swap battery) so that by the time you get in and start it, it should be ready to go. After 15 minutes it should go into deep sleep.
