Backlight While in VA

Enables the radio's display to have its backlight continuously on when the radio is plugged into the Vehicular Adapter (VA). Any key press that would normally affect the status of the backlight is ignored (see also Auto Light, Independent Top Light, and the Light / Flip (Display) button-press). When the radio is removed from the VA, button-presses affecting the backlight resume normal operation.
