This is a link to the online manual for the Touch 7. http://www.lowrance.com/Root/Lowranc...0312-001_w.pdf

If you scroll down to a pages 16 and 17, Customizing pages, it will take you through this. On page 17 it shows the different screen configurations from 1 to 4 screens per display and numerous ways to align them on the page. There are 7 different screen options on page 17 and that is where you select where you want each display shown, i.e. side by side, over and under, etc. Best to do this sitting in your yard with the book in your hand. Too many distractions on the water. I would see things while out on the water that I did not like and then come home and fix them in the yard.
This thing has so many different features, it is hard to digest at one sitting, I can promise you every time I go out I see something else I want to change and usually can't figure it out going down the lake.
