Adjusting Screen Brightness - TDS GTN 750 - Too Dim

[Jim in Ohio]

I find the GTN 750 screen to be very dim. The brightness setting in the GTN 750 settings is set at 37%, but there seems to be no way to adjust this setting. The dimming control knobs on the Bonanza panel are all turned up to full brightness, but I've been known to overlook the obvious before. Does anyone know how to turn up the screen brightness on the TDS GTN 750?

I have the PMS version, but they should all work the same. From the home touch screen (where Map is in top left)
Press System
Press Backlight
and basically play with the settings there to get what you want.
