I did not see this request on the forum so I figured I would add it. I'm guessing that Furuno already knows that many people would like to see some upgraded options. In my area, that probably means the newest Navionics Bathy charts working on the TZT3. I'm sure other areas might be different. Below is a link to a current discussion on another forum.
