Surprised that my clock didn't update off the GPS for DST I had to fiddle around to find the Time Setting. I noticed the first entry was set to +2??!!? This didn't make any sense at first. I live in CST/CDT time zone which is REALLY -6/-5. So why was it +2? I'm guessing this is some kind of Microsoft thing as it seems 0 is really PST/PDT (-8/-7) and since these radios are MS embedded OS I guess it thinks Redmond, WA time is 0 offset.

So MS uses Seattle as it's prime meridian??? I suspect that string was just some un-initialized garbage. GPS doesn't know anything about local political things like DST or when it changes. Hence the "Summer Time" toggle in Regional Settings.

On a related note, it would be nice if the HU would adjust to the correct local time as you drove across time zones. Probably is more complicated than it sounds.

A new install of windows always defaults to PST or -8. Since it's a "GPS" it should have knowledge of where you are and what TZ you are in. Also MS OS's can tell when DST starts and ends and sets you PC automatically so again it should be able to do this on the radio. I wonder if the APP radio from Pioneer handles it? If it's based on MacOS's they can handle off this stuff. I've never had to set the time on any MAC. It even figures your TZ at home without any GPS based on your public IP.
