Symptom: Clock is off by one or two hours

My clock is off by one or two hours or time shown is incorrect.  How do I set my clock?

First, press “CLOCK” from the main menu and check the DST settings, which can be manually configured by selecting ‘DST OFF’, ‘DST +1’ or ‘DST +2’ depending on your time zone.

Times displayed on Unavi system is automatically set by receiving GPS signals from satellites and maintained by a clock circuit called RTC (Real-Time Clock).  If the system has been turned off for a long period of time and/or left in an area with no GPS signal, please give some time until the initial system boot-up is completed and move the vehicle to an open area where signal can be received to adjust to current time.  A GPS receiver can shorten its startup time by comparing the current time, according to its RTC, with the time at which it last had a valid signal.[2] If it has been less than a few hours then the previous ephemeris is still usable.

Note: On certain models, the clock shown on the radio display screen must be adjusted from the setup menu of the factory radio.  Please refer to the vehicle manufacturer Owner’s Manual.
