neil thank you for good clues. All I've found so far was about that the locale setting (after hard reset) is influencing the color of the upper bar (and as well the speed icon). But only for nuvi units (despite the fact that the application inside the kenwood and nuvi is the same - at least the appearance)
I fear that crossflash is not possible, because there is no full firmware flash for kenwood units. Just updates. And Garmin fw is part of the kenwood one.
But the safest thing I could do is to load NA map as you advise, I'll be back with observations.
If someone could confirm or deny whether the locale setting is present in some file on the Garmin filesystem or not, I would be grateful.
EDIT : I was unsuccessful, I was trying the AU map and despite it loaded seamlessly, there is no change in the UI color. Moreover I've found that map updates for this unit (DNX4230BT) are run just from SD card and are not copied in the internal memory.
