Dear developers, Are you aware of the criteria that a garmin unit (I'm using a Montana 600) is using for Auto-Zoom? There is not much information around on the internet. Some tell something about speed. Quite many tell that zoom is done to the extent to include the next turn activity. Some tell that routing has to be active (I had some auto zooming although I wasn't activly routing) Computerteddy couldn't help . I'm asking as I drive some road for quite a while/distance and the unit doesn't zoom out but sticks to the 50m-scale. Although at the beginning of this part it switches to the 200m scale for a 1 or 2 of seconds. Which would be ok for me for at least the next kilometer. So I wonder why it doesn't stick longer to it. Is there something with the style or the typ-file to be considered? Or a setting in the unit? Appreciating your comments Best regards, Michael
