There was a small display screen in the Falcon cockpit. I presume for the Navi computer? It’s seen (and heard) being used in ESB, but we never actually see what they’re looking at, so darned if I know where it actually is on the console.

You can see it on set in this BTS pic:
Luke’s Landspeeder was intended to have a scanner display, and animation for tracking down Artoo was actually made but was cut.
