Hi Dean,

Is this using the zoom feature on the Navman, or is it the bottom lock? I have been trying to work out how to focus the main screen on my Navman on only the bottom 10m however I have been unable to do this, it appears that it can only be done in the split screen.

From your pic it looks as if you use the small right hand section to stay in toouch with the bottom and then use the larger "split" to focus on the bottom.
