Alright... I can't find any way to set the clock through the steering wheel controls, or through the head unit. The head unit touchscreen asks me to select a time zone, which I have selected the correct one. But the clock is displaying time about 3.5 hours ahead of my current time. It's not even close within an hour, which makes me think it's not just getting the wrong time zone. The GPS detects my location normally. Also, I let this car sit with no battery for a few weeks while I replaced the head gasket. It has a good 12v battery now. I have the GPS owner's manual and looked through there, with no avail. (I don't have the owner's manual, it didn't come with the car.) I did a quick search but couldn't figure it out from that either. Help me out Prius bros!!
