Silly question. How can I adjust the time on a 612 OTO?
Press the menu button on the Bose system, turn the big knob until "System Options" comes up, press the button, turn the big knob until "Time and Date" or something like that comes up. I've had mixed success with the semi-automatic time and date setting feature, and it didn't seem to know about daylight savings time this year. Where does it even get the time? Sometimes it's off by several minutes.
Actually I ended up downloading a YouTube video for a 2009 Maserati which is very similar to the 612 and yes, got it working!
