How to Manually control Brightness 700TSV
I have a Xenarc 700TSV installed in my car and got the desire to control the brightness by the car's dimmer switch. This would allow me to manually turn the brightness up and down with out designing for extra functionality of extra properties.
If any one knows how the 700TSV's brightness is controlled on the screen, or can tell me how to control the brightness.
I cannot use the remote that was included with the screen, nor the buttons on the buttom of the screen because of stylistic design.
