Gogo Posted December 18, 2008 Share Posted December 18, 2008 The navigation in my 07 IS250 always has the arrival time an hour ahead of the actual time of arrival. Example: If I set my navigation at noon for a 4hr trip, the arrival time on the navigation system will say 5pm. The navigation says it is a 4hr trip but still has a 5 hour time of arrival. I hope this is clear....my question being is there any way to set the time on the navigation system itself? I am set in the proper time zone FYI AND I have the speed settings on the roadways set at the speed inwhich I drive. The lady at the dealership said that in time the navigation system will adjust to my driving tendancies....???? Quote Link to comment Share on other sites More sharing options...
Step Hen Posted December 18, 2008 Share Posted December 18, 2008 You may want to check the daylights savings time settings, but I think that the nav gets it's time information from the GPS signal... Quote Link to comment Share on other sites More sharing options...
terry993 Posted December 18, 2008 Share Posted December 18, 2008 Have not read the manual, but could the GPS be tied into the dash clck? Quote Link to comment Share on other sites More sharing options...
linn Posted December 18, 2008 Share Posted December 18, 2008 Yes, it's definitely the daylight saving time-setting in the menu. I have to change it twice a year ;) linn Quote Link to comment Share on other sites More sharing options...
