As i understand, add-ons like X-Life are needing navdata and i would also like to update the navdata of the XP default gps.

Do i need to buy navdata or is there free - of course not the most current - navdata for X-Plane/X-life?

I'm not sure what the current AIRAC cycle is that's included with XP11, but to keep it current, you will need to pay for it. I believe both Navigraph and Aerosoft have subscriptions. I'm hoping that every now and then the cycle will be updated when they update X-Plane.

Thanks Tony! So if i buy this, i will be able to update X-Plane?

I believe so, yes. It seems only recently has it been updated to the XP11 format, see:

OK, i did buy it from navigraph I did install the manager software and i did install the current navdata to XP10 and XP11:

But if i open the defult GPS, it says that the navdata would be out of date:

How can i test if the navdata has been installed correctly?

 

EDIT: 

OK i think i have found a solution in this thread: http://forums.x-plane.org/index.php?/forums/topic/110162-updating-new-nav-data-navigraph-for-x-plane-11/

Thanks for solution. I will test this tonight.

It seems to work, if the navdata is installed to the "custom data" folder.
