The only other issue I have encountered so far is that I've had trouble with the autopilot approach hold working correctly. Sometimes it does, sometimes it does not. The issues being that it tracks s-turning back & forth on the localizer after capture and sometimes does not capture the glideslope at all. The instruments track perfectly and flying the ILS by hand with the new instrumentation is a vast improvement over the previous version. I tried a couple of adjustments to the A/P section of the config but to no avail. As far as I can tell, the remainder of the A/P controls work pretty much flawlessly.
