Greetings KC2400, your input is valuable to us. The data bar you reference on current TZTouch2/3 products is a "route bar" and comes up when engaged in a route or navigating. The data box on the left of the TZT2/3 is actually improved over other versions and now you can add a nearly unlimited amount of sensor information in that data bar. Accessing the same information on each application page (Fish Finder, Radar, Plotter, etc.). Our data bar can be scrolled allowing more data to be stacked on top of data. A data bar located above may be limited and possibly busy with the route bar. However, I'll recommend your suggestion to product development for further consideration.
Hope this helps,
