How do you change the clock to account for the time change? On my RX400h you hit the INFO button and there is a button that says Adjust Clock. But on the IS F when I hit INFO there is no adjust clock. Then on the MENU under setup I see the Time Zone setting. But I tried Daylight Savings both on and off and it has no affect on the time displayed on the clock. I'm so confused!!!! And too lazy to read the manual.

Just hold the hour (or minute) button. It will eventually increment.

^^That's what I did this morning to change it I didn't know there was even a way to account for daylight savings time!

They didn't add that feature in the ISF because it added to much weight to the car. HAHA just kidding. Not really sure about what you're referring to. I just manually changed mine. Good luck

IIRC go to the NAV settings and change the time zone, that's what I did last Sunday.

Yeah, I noticed that too.

My wife's RX400h gets the time from the GPS signal. All you got to do is tell what timezone you want it to display.

The ISF clock is just a plain old clock, not hooked up the GPS at all. Weird, you'd think it would be the same. I like the GPS sync feature, means the time is always accurate.

I don't think so, I believe the clock is tied to the NAV system. On the NAV settings you change time zone (even though it should know already from your position) and daylight savings, but not time. When you change the time on the clock it changes as well on the NAV.

Thanks for the responses. I did the hour button thing since the day light savings setting in the time zone setup didn't do anything.

Our navi tells time?
Unless the ISf is different, you have to change it manually, the clock isnt in sync with the GPS. I think the time zone setting you are talking about is the region settings.
