I have a RX 350 2007 with Nav System. Daylight Saving just ended but the clock still is stuck with DST time. I thought the clock is auto synch with GPS. And I looked and looked and looked and could not figure out a way to manually adjust the clock. For models with no nav system installed, there are three buttons below the clock. But my clock does not have any buttons below. What bothers me the most is that I called my dealer and they had no idea. Thanks in advance for any help.
