    Default Change the Map Color?

    Newbie here. First forum post ever.
    I recently bought the garmin 2792. Is there any way to change the map color for non-urban areas? Being that I'm in Ohio all non urban areas are an ugly yellow-greenish color that is awful. Changing themes only seems to affect the urban areas, I've even downloaded and created custom themes, trying to alter the map_land_clr with no prevail. I'm using the 2015.10 maps. Called Garmin support, they told me that's just to way it is. Thanks Garmin. Any advise?

    I can produce the above result in Mapsource and Basecamp by adding to the map's TYP file the polygon 0x4b (Map Background or Data Bounds) without any Draw Order.
    When I transfer this map to my 3490, 205w, GarminMobilePc and Streetpilot Android the result is that this polygon is shown transparent (????)
    When I do the same to a nonNT map, the same polygon is shown as solid, filled with the color of my choice.
    It's like the NT map cannot read the 0x4b polygon, like there is another polygon for Map Background when the map is NT.

    But if I use 0x10d01 polygon as Map Background, things start to look promising!!!
    I will look into it....

    The first screenshot is the map with default TYP and Garmin Theme (transparent background, 3D basemap is shown or the yellowish color on other devices that do not support 3D)
    The second screenshot is the map with changed TYP and German Theme
    The third screenshot is the map with Changed TYP and Garmin Theme
    The custom color for the background is green-yellow

    Next time you call them, tell them that CAN BE DONE, but first tell them to correct a HUGE MISTAKE in CNNA 2015.10.
    Because you live in Ohio you will not fail to notice that 22 map tiles to the east, are designated as Town polygons (the tiles!!!!!!!)
    You can see them at close zoom that they appear "grey" as Town polygons with the original TYP

    In most maps, the background type is 0x4b for a non NT map and 0x10d01 for a NT map.

    I can produce the above result in Mapsource and Basecamp by adding to the map's TYP file the polygon 0x4b (Map Background or Data Bounds) without any Draw Order.
    When I transfer this map to my 3490, 205w, GarminMobilePc and Streetpilot Android the result is that this polygon is shown transparent (????)
    To avoid some issues, it is advisable to add that polygon ( 0x4b for non NT map or 0x10d01 for a NT map) to the draworder list ( in the lower level i.e. 1).

    Yes, I agree, that's what I've done, but this polygon is Map Coverage and not Background and covers the entire map.
    So I had to use the City polygons (draw order 2) and all Lake, River and Ocean/Sea polygons (draw order 3) in order to have a fine result!

    Those polygons are the ones that are displayed when no other polygons are displayed, they are usually called "background" and , of course, they cover all the map. I don't understand why you write that it is not the background.
    If no other polygons are displayed and if those background polygons are not displayed too (or are transparent) , then the screen is black.

    So, to change this yellow back color, you only have to add this background polygon to the list of polygons and to the draworder with the value 1. And finally you have to increase all other draworders to 1 (only the background must have draworder=1)

    The problem is that CN Typ file is empty!!!
    So if you add 0x10d01 and draw order 1, this polygon covers the entire map and you have to manually add all City and Water polygons and give them draw order 2 and 3 so that rivers are drawn over city polygons.
    You have to add all ot them, because we don't really Know how many of them Garmin uses in the CN maps and nobody can visually check so big maps see if anything is missing (not drawn).
    But because of our nice conversation here (thanks for the ...trigger ) I tried something i've never done with CN.
    I added 0x10d01 with no draw order and the polygon was drawn under all other polygons which kept their default draw order!!!!
    So instead of adding 30 or so polygons and altering their default draw order, we simply add one polygon with no draw order, much easier especially for people with limited experience with Typ files.


    EDIT:
    This works fine with the 205w and 60csx
    With GarminMobilePC the City polygons are drawn under the background polygon, everything else is OK
    With 3490 unfortunately it doesn't work at all, the background polygon is transparent or not readable by a NT map, because I use this "no draw order" trick successfully with nonNT maps when I don't want to alter the default draw order of the other polygons.
