I fly both the Fenix and the new Inibuilds, don't know what your problem is, sure procedures are a little different but not much, the one is CEO the other NEO of course, and of course the Simbrief interface is just a little different... Even so, the Inibuilds is brilliant, I've flown many flights in it. It's a no brainer to follow LNAV, you push a button π
