I have noticed all the negative posts about the ARNAV unit but have seen relatively few about the Century HSI units; both vacuum and electric. It seems there have been MULTIPLE problems from many owners using these units. I know of one case where the airplane is less than 6 months old and the HSI has been replaced FOUR TIMES already.
Since the HSI displays the primary Nav data, if the unit fails, unless you have a “C” package, you lose all ILS capability. The Garmins have been very reliable but their weakest link seems to be the display unit they use; the HSI.
Since Cirrus now offers the Sandel unit in the SR22, why not have it as an option or even “standard equipment” on the SR20. When you compare the price of the Sandel vs the Century, there is not that much difference as it turns out.
What do you folks think? I would much rather have a Sandel than a Century based on what I have seen so far.
