Will it be possible to view Navigraph IFR maps in the G3000 and/or G5000 anytime soon? It works very well in the G1000 NXi. 
Hello, welcome to our forum!
This is a good suggestion and one that we have thought about internally as well. We have not got the resources to do it at the moment, but that might change in the future - especially if this topic happens to gain more votes!
Feel free to vote for it yourself!
Kind Regards,
Malte
