In-vehicle display system

摘要

An in-vehicle display system includes a steering switch disposed at a steering wheel, an in-vehicle display having a display screen, and a touch panel covering the display screen. When an operator operates the touch panel, the in-vehicle display is operable to display a touch panel menu including icons on the display screen. When the operator operates the steering switch while the touch panel menu is displayed on the display screen, the in-vehicle display is operable to replace the touch panel menu with a steering switch menu to display the steering switch menu on display screen. The steering switch menu includes the icons arranged differently than the touch panel menu. This in-vehicle display system is suitably used to operate both of the touch panel and the steering switch.
