> May I ask how often an inland cruiser needs to update?
In practice you certainly don't need to update each year - every 3 years or so is OK, but they will still charge you "by the year" when you do upgrade, so €65 per year since your last upgrade. Economically therefore it makes no difference unless you plan to stop barging soon.

This is where they force an upgrade on you! If your version is more than about 3 years old, you get a pop-up screen saying that your version is no longer supported when you ask for or are offered the latest stoppage information.
I've upgrade twice since my 2008 purchase, but it's cost me just as much as if I'd upgraded every year. In fact a bit more as, when upgrade prices increase, they increase retrospectively!
In my view Navigo is such a good program to have, both for route planning and cruising, it's a cost worth paying - but don't ever lose your dongle.
I am about to trial Navigo for 2 weeks but notice that the annual updates are not cheap.
May I ask how often an inland cruiser needs to update?
They have updates for the software, seemingly annually, but presumably if you are happy with it's operation then that would not be essential?
(the latest update seems to be mainly relevant to the Rhine)
Also, I doubt the Eastern French canal network changes much these days, so map updates may not be essential every year?
But if you do not have the latest updates does it still notify you of short notice closures/chaumages?
