I did a long night flight last night and the brightness of the 430s (2 of them) was overwhelming in the darkness. I left one on and restarted the other in the setup mode to see if I could affect the brightness. I could affect it a little, but, really not enough to matter.
The unit needs a manual adjustment for brightness.
The unit needs a better design for replacing the battery in it also. I had the battery replaced in one of them and the entire unit needs to be disassembled and a new battery soldered in place. Really difficult to replace

Gary,
I've experienced the same problem. I was able to tone down the light by adding one of these to the screen of the Garmin 430.http://www.aircraftspruce.com/menus/av/gps_zscreen.html

Might help in your application too.

Years ago, I replaced a battery in a Power Mac that looked exactly like the battery in the 430. I think the battery was 5 years old in that one too. The battery was $12 and took 5 minutes to replace.


Garmin needs to hire Steve Jobs.


Question: Is there a simple, straight forward way to dim the 430 screen at night?

Looking at paragraph 5.3.7 in the 400W series installation manual, it looks like you can tie the display and/or key lighting to either the 430's photocell or to a DC lighting bus. There's also a minimum display brightness setting. Is that what you changed? There are also several other settings, including SLOPE and OFFSET you might look at.

When I went to the setup page, there was something about slope, . . . . I forget. Anyway, it didn't seem to make a hoot about how bright the display was.

I'll look into it more today.
