GRT Connection

[SMO]

I have the EFIS AP IV, and I am using a GRT (HS) EFIS as a backup. The AP will be driven from a 430 or a 696 - I have both. Depending on the failure mode (screen failure), there is some potential I would want to command the AP from the GRT. Is there any connectivity that would allow this?

The integrated AP in the EFIS can only be controlled through the EFIS. It has no provision for external control. Thanks!
