Initial impressions from first time Garmin:
1. Add more combo templates and/or allow user to customize. Lowrance has done this forever.
2. Allow pages (sonar or chart) to be used more than once in a template. eg. allow side vu to be used in 2 different panes of a 3 or 4 pane combo view.
3. Add an option to TURN OFF the networked Echomaps on and off feature. (multiple networked graphs power up and down all at the same time from the touch of a single unit).
Bought this setup for Livescope. so far, very impressed with that!
