Yes, the 12V wire is switched by ignition. Sorry I can't recall the color code for the wire, but it probably wouldn't match yours anyway. As such, it is fused at the fusebox, so the in line fuse on the WOOX yellow wire is probably redundant (but safe) .
And yes, the blue turn on wire is connected to the head unit's antenna trigger wire (Blaupunkt Denver).
As an aside, I'm using the original Hirschmann antenna unit, but the electronics have been replaced with those from an aftermarket antenna, and thus uses the more common 3 wire set-up (12V power, 12V trigger, ground) (that's another reason why my dash antenna switch isn't used).
