Hi Gerd

I used these options:

x-dem: G:\mkgmap\DEM
x-dem-dists: 3312,6628,9942,13248,44176
x-overview-dem-dist=88368

The strange thing is that the img is compiled without errors but not rendered. This issue/bug is not happening in r-4066 so I guess it is "solved" but you never know.

Hi Minko,

Hard to say without detailed information about the used dem options.
Errors in the dem encoder potentially cause buffer overflows/underruns in Garmin software.
Maybe you can post the options used with r4025?

Gerd
