I'm having trouble resolving the two images I'm seeing as being the same-but then, I guess that's the whole point, eh? (g)
In the photo the minutes are a little hard to read, but it's set to dd°mm'.mmm. You can see (upper right) that the distance from the vessel to the waypoint is .933 nm, confirming the image scale.

The islands on the screen are the only ones there, but you're right. The shape on radar does not precisely agree with the map. However, the shape of the islands in Rains' Mexico guide conforms more to the radar than those of the charts. It was hard to tell the shape of the islands visually, but the angles we could see seemed to match the radar.
