JCV full screen & JCV lane Assist Full in post #1

with them both being picture size 480*270
More jcv images in the larger file as said by Smokefree. The small one is maybe for Western EU only[?].

I think the sole OEM CN EU mapping for zumo 3x0 is the unicode version: [Only registered and activated users can see links. ] [it uses split-screen JCV file].
