IIRC part of the installation (and the later AD) is to establish a

paperwork, and it should give you a good understanding of when and
to what degree it's likely to be helpful.

If it's the Precise Flight STC, it had better be placarded on the panel, else
your aircraft is not in compliance with its type certificate.
