That's what's needed. It works for all the other cameras I don't have control over...
There's a real problem with a mature product like a car, in that there is nothing other than brand loyalty really to select one over another, so the manufacturers stick pointless extras on left right and centre. Sometimes it's vaguely useful, mostly it's just pointless crap with confusing and distracting features. In this case, every one of the control functions listed (with the exception of spying in the cabin, of course) has been available for ten or twenty years just by issuing Junior with a different ignition key.
On the bright side, the chance of it working for more than a few months it probably pretty low. The 'smarts' on my 2008 Eurobox regularly lock up and require the car to be stopped and restarted... Probably there are failure modes which require me to close all the windows, too, though I haven't yet found them.
