Overview

Updates the application's display text area, regardless of whether or not this text area is visible to the user at the time of the request. The application's display text area remains unchanged until updated by subsequent calls to Show

The content of the application's display text area is visible to the user when the application's com.smartdevicelink.proxy.rpc.enums.HMILevel is FULL or LIMITED, and the com.smartdevicelink.proxy.rpc.enums.SystemContext=MAIN and no Alert is in progress

The Show operation cannot be used to create an animated scrolling screen. To avoid distracting the driver, Show commands cannot be issued more than once every 4 seconds. Requests made more frequently than this will be rejected

HMILevel needs to be FULL, LIMITED or BACKGROUND
