The Z3815 doesn't store the surveyed location so at every power on it has to survey again. It is supposed you leave it on forever once installed. Strange date: the date reflects the fact that the Furuno GPSes have a 1024 weeks rollover correction that was designed in 1993 and past 19 years it reverts back. This "bug" was discussed here 2 weeks ago.
