I just purchased a Garmin GTX-327 off of Ebay (installed for one day, before
the owner decided he REALLY wanted the Mode S GTX-330!), and am lining up
installation. I was surprised to hear that a 337 form had to be filed for
this installation.

It's not a big deal for the avionics shop to do, but wouldn't you think
Garmin would have STC'd this unit for the Cherokee line?
