Setting Time On Nav

[abaquilar]

Please help, I've tried looking through the manual but can't seem to find out how to change the time on my NAV system. I live in California and ever since the 1hr "fall back" daylight savings time shift my system clock did not update even though the "day light savings" setting is on. So now it reads on the system (estimated arrival time) to be 1hr more than it should be. Any help or suggestions would be greatly appreciated. thanks.

Get to the "setup" screen, and scroll down until you see, "Time Zone", than click "change".
