LEX5 / LEX5LS / LEX4 / LEX3 / LEX3L / LEXGS / LEXGX - while in VLine mode simply press FM. The FM overlay will appear at the top of the screen.
LEX7 / LEX89 / LEX9: You can go to the FM radio source, then press and hold MAPS (or MENU if MAPS is not present) for 3-5 seconds, and then the VLine should appear.
