What are you looking for? Not all upgrades are (1) technically possible on "other edge models" or are (2) benificial for every user. For example, the way Garmin has killed the larger white GPS position cursor when the Edge is in map High Contrast Mode. No thank you for the Edge Explore - please leave it unchanged!
Or the direction arrows on loaded courses: please NO, or at least configurable, i.e. ON or OFF and size.
Generally, efficiency gains are always welcome. Specifically, the Edge family's latest update integrates route direction arrows for the loaded course. This is such an elementary improvement to the map interface i expect most will approve. I certainly do.
