I just came across this NOTAM. that must be a joke regarding the prices Collins seems to charge for their stuff:
EDWW EDGG EDMM GNSS AREA-WIDE OPRATIONS B1696/17

In all fairness, there are some similar problems with Garmin boxes.
The underlying problem in my humble opinion is the rigid certification regime for aeronautical systems, which made sense when the most complex piece of equipment in a panel was an HSI. But with today’s electronics, it is on the one hand impossible to prove that they work in the desired way on initial certification, but it is just made a lot harder to fix problems later as it is standard procedure everywhere else where IT is involved. All the while there is no financial incentive for avionics manufacturers to provide longterm support that would keep things up to date such as my Macbook, which I just upgraded to the latest OS version (for free of course). ;)
There is a serious software problem with proline 4 and 21 that in very specific circumstances means that an aircraft could turn the wrong way on an approach. As a result they have deleted 1/3 of the approaches. It isnt a database issue and only arises when temperature compensation is done and preset altitudes are changed.
