Thanks for setting the record straight Matt.
Below is the old thread that talked about tying these togther, I knew I'd seen this come up before:

Steve,
I know we talked about this in a separate email, but has the Garmin team concluded that both the G3X and 650 TOGA lines can be tied together using a spst switch?
Hi Bill,
As we discussed, we have been using a simple SPST button in our G3X show displays for the TO/GA button wired to input discretes on the GEA24 or GSU73, and GTN 6XX/7XX for some time with no problems.
We studied the electrical design of these inputs and decided that it was fine to tie these pulled-up input discretes together and use a SPST button switch to ground instead of the DPDT that isolates the two input discretes.
Thanks,
Steve
