Did mine before EASA was relevant (but not very long ago).
After a ground training session, then a 35 minute flight in VMC, then a one hour flight most of which happened to be in IMC (with a single ILS approach) I got signed off for both VMC and IMC ...
... hmm, I thought, no, I don't really feel like diving straight off into clouds on my own, that's not enough. Since then I've done around another 14 hours on my own, including an ILS approach with a "competent observer", with no problem at all, and some GNSS approaches with an instructor. I would now feel no more unhappy flying into IMC with the G1000 than with steam gauges. But I'm not sure I'd take passengers into IMC yet.
The Max Truscott CD-ROM I found useful.
I now book a G1000 aircraft in preference whenever I can get it, it makes navigation so much easier ...
