.
Agree on the ELT, as covered above
Also agree on which HTAWS system was installed. As noted, it could have been the GNS 430 or 530 on board system. I wonder if it had annunciators, aural warnings. And if it was easy to identify which box (assuming it was a GNS) had the system activated.

As for the elephant, the other two points are minor compared to that one....
