Default Garmin GTN 650 to Garmin 245 audio panel

[IMG][/IMG]
Good afternoon!
Since there are no numbers on the installation diagram I'm assuming that I need to find pin (com 1 audio out Hi) on the GTN 650 to connect with pin 9 (com 1 audio in HI) on my Garmin 245 audio panel. Makes sense to me, what say you?
Thanks!
SteveL
