Same problem here. This plane has pretty much sat in my hangar since buying it a few years ago.  Reason has been reliability, namely it won't start, but then it will start but there is no way to tell why it did.  Would be good if CS had an answer on this as I am far from alone - i.e. we DO all follow the manual and the tutorials (which are very clearly written) but cold & dark starts continue to be hit or miss.

Got her out yesterday for the first time in ages and managed this time to start her up (odd numbered day of the week perhaps) took off and then had these same avionics failures.  I already have the default C172 with everything off except for avionics set as the default flight and also have a key mapped for master avionics.

Why can't CS even post here to say they have these tickets and are working on it?  With so many other payware aircraft these things often get quickly gang tackled by this kind of group discussion on a forum by the devs and customers together.  Results in nice warm fuzzy feelings all around and one would expect customer goodwill and future sales.  Don't get me wrong, I have the Herc, the 727 and 707 and think they are amongst the best payware, inside and out.  It's just that there is a kind of odd robotic like manner here, not wanting to communicate easily like normal adults do and should. ;)
