I am posting to see how others addressed dimming Garmin components such as the GTN6XX, GMA245, and the GTR200. The rest of my avionics are from Dynon.

The Garmin components all have reference voltage inputs to externally control the brightness of the screen, button text, etc. They also have an internal photocell if the external source is not utilized.

To further complicate things, Dynon has a "Dim OUT" pin on the HDXs. This is a variable voltage output reference that can control the brightness of other components that have a "light in" such as the Garmin products. Dynon did state that there is a possibility of noise on the audio panel if the grounds are not referenced correctly.

How have others addressed this, and how are your results?

No comments?  Surely others have some Garmin components integrated into their Dynon suite.

Guessing the rest of us are fine with the built-in dimming.

Ahyup.  One less thing to break.

That is the response that I was hoping for.  Many less wires to add.  Just wanted to make sure that someone did not state that having the units dim independently was annoying or some other issue.

I used the Dynon SV-KNOB-DIMMER and connected my GTX335 and GTR200 to it along with the Dynon Skyview. I had to adjust the dim values of each component but my whole panel now dims using the SV-KNOB-DIMMER.
