Problem
Things to try
After rebooting MARC, my
preprogramed destinations are gone,
and the buttons appear grey.
In Active Map Mode, this is by design; MARC does not retain maps or
locations when powered down. Since programming is extremely easy,
simply manually push MARC on the next route and reprogram the
destinations. Note this includes powering down to change the battery. If
you need the map and destinations to be saved, consider Fixed Map Mode.
Operating modes: Active and Fixed
