These (changes for “colors and distance alerts”) would be features of the head unit. Not the radar device. The radar device certainly isn’t transmitting what color to use on the head unit (which could be monochrome). It seems the only display option Garmin head units provide is which side to display the dots (regardless of what company’s radar unit you are using).

The different radar devices provide the same standard data, which is how they all work with Wahoo and Garmin head units.

The Trek device provides additional data about lateral position but no head unit can display that data (at present).

It might be possible to write an app for the Garmin head units to show the extra data. Garmin is the only company that allows for custom apps. (Hammerhead/Karoo allow for custom apps (since it’s Android) but not officially (AFAIK).)
