Description of the issue: None of the key binds linked to the zoom controls of the GNS 530 and GNS 430 work. There also appears to be duplicate/triplicate controls for zooming the GNS (see pic).

FREQUENCY OF ISSUE
How often does this occur for you (Example: Just once, every time on sim load, intermittently)?
Every use
REPRODUCTION STEPS
Please list clear steps you took in order to help our test team reproduce the same issue:
Load game (in stock C172). Although this issue is not limited to the C172.
Associate any of the GNS 530/430 zoom controls to a keyboard command (those shown and highlighted in screen grab).
Test the key bind and observe if the GNS unit zooms in/out.
YOUR SETTINGS
If the issue still occurs with no mods and add-ons, please continue to report your issue. If not, please move this post to the User Support Hub.

Now there are 3 issues documented with the wiring of GNS-buttons that needs work, for basic functionality:
