Вот что нашел на приусчате:
The NAV time (GPS) offset is configured through the setup screen on the NAV:
1) Get through the "I agree" screen.
2) Press the MENU button on the MFD.
3) Press the SETUP soft button on the screen.
4) Press the TIME ZONES soft button on the screen.
5) Pick your time zone and whether to use daylight savings time.
This sets the GPS offset to your local time.
As for the dash clock, as the other poster says, it's just a dumb LED digital clock. Use the push buttons to set it.
