I noticed yesterday that the time did not switch back to standard time. I thought maybe it needed some time to connect with my phone or sat system to correct, but didn't happen. So today I went into my clock settings and saw that DST was checked. I unchecked it and my clock then changed and displayed correctly. So, does that mean that DST time changes are not automatic in this car? And you need to check or uncheck DST with every time change?
