- a display;
an input device;
memory arranged to store display settings of the display for at least two ambient lighting conditions, each said display setting comprising a color scheme to be used in a navigation view of the navigation device and a brightness setting, wherein a first display setting is suited for conditions and a second display setting is suited for nighttime conditions; and
a processor arranged to;
monitor and evaluate a signal indicative of a current ambient lighting condition, said signal being at least one of;
a signal from a light sensor; and
time data;
select the stored display setting for the current ambient lighting condition;
determine if a current display setting is the selected display setting; and
automatically change said current display setting to said selected display setting, if said current display setting is not said selected display setting;
wherein a first display setting of the stored display settings comprises a daytime brightness setting and a second display setting of the stored display settings comprises a nighttime brightness setting, the daytime brightness setting and the nighttime brightness setting being based on a received portable navigation by a user on the portable navigation device, comprising a selection of a brightness level to be used during daytime and a selection of another brightness level to be used during nighttime, wherein the selection of the daytime brightness level and the selection of the nighttime brightness level are made independently from or as a ratio of each other.
