I will certainly check into this.  But the problem brought up a
limitation to my panel - lack of ADHRS redundancy.  I started shopping
and found that a second Pinpoint might cost $17k whilst a
new-and-improved Crossbow 425 is about $3k.  I'm now considering the
current Pinpoint running screens 1 an 3 and the Crossbow feeding screen
2. (after we have traced down the current problem naturally). =20

Thoughts?

Robert,  you have a problem and you need to identify the source.  . . .
My strong recommendation is that Robert take steps to find and eliminate
the source of the failure. The "wait and see" approach is unacceptable.
If a fault happened then it happened for a reason and that reason, at a
minimum, must be identified. Contact the avionics installer and  relate
ALL information surrounding the fault. He should download and forward
the log files to CFS for analysis.=20
