Mine definitely says 3.63. Both on bootup and when I press Done + Up. Hopefully they haven't introduced any new restrictions... If they have I'm returning the unit.
And as far as bootup, apparently the simplest method is to press DONE long to get it to start displaying data.
Otherwise you can press "done" button repeatedly until it says "station 1", and then holding the done button long. It then shows the normal operation screen with an "R" at the bottom right, and after about 30 seconds it starts regularly receiving and displaying data from the ISS.
That's a bit complicated, but fine if its the same person always tending the unit. But if installed in a multi person environment, like a business, a bit unnecessarily complicated. Nothing a label applied to the bottom of the console won't fix, but in a perfect world that wouldn't be necessary.
