How to adjust this analog clock then?
I agree with the other posters: it has to be done twice a year because of DST, but it's really easy: once in settings - time, the easiest is to choose the "use satellite time" (or something similar, i don't recall he exact wording) option: you'll see the clock's hands adjust automatically one hour forward or back as required.
I don't know if it uses IRIG or another signal but it's just a display.
I think you can adjust it manually but I never have. I don't know if it's regulated. I think it's just a stepper motor.
That's all in the FAQ somewhere.
The other inputs are probably signal wires from the NAV. The Bentley wiring diagrams would probably show where the wires connect but not what the signals are. They may be time code signals or may be some special car clock or even Phaeton and Bentley only car clock signals.
I don't know if it depends on the signals or if it will "keep" time with just voltage. If it did move the hands at a predetermined rate, how would you set it?
When my first "Atomic" clock couldn't find a signal, the hands just spun around at high speed. I was trying it overseas and it was looking for the radio signal from Colorado. It had no way to set the hands manually.
You could buy an "Atomic" radio controlled clock (with hands, AKA "analog") and try using its signal wires on a Phaeton "clock". They are pretty cheap now.
GPS satellites send time information but I don't know if radio controlled clocks use the same signals. (I don't know if the Colorado transmitter or other transmitters send out IRIG signals.)
There was a Phaeton "clock" on eBay with the cover included but it probably sold by now. I think it was Burr Walnut.
