Hi Joao There isn't a way to change the type of the background polygon/area of map coverage. Can you disable the night-mode switching in your device? Can you define the rendering for the 0x4b polygon in your typ-file, with both a day and night mode? Transparent maps don't set the background. Could you have define another map, loaded underneath, as just a single, lighter, colour? Hope one of these suggestions help, can't think of anything else useful to say Regards Ticker On Tue, 2023-08-22 at 21:35 +1000, Joao Almeida wrote:

I'm still working on translating my style and typ file to a version that the Garmin Tread is happy with.

But I found a new issue, this time with polygons. Normally the (non mapped areas) are drawn by the x4B00 polygon with a draworder of 0. However the Tread does not render the 4B00 polygon, in day mode there is no issue but in night mode those non mapped areas are completely black. ( and there are lots of them ) for example around all the map highways and other areas. It's more of an annoyance than anything else.

But is there a way to change the tag that mkgmap gives to non mapped areas? for example the x2700 polygon instead of the x4800?

Thanks
