Display zoom level of lines

[ontheroad]

Hello Guys,

I have noticed that some line types are not displayed on the XT in certain level of zoom according to the zoom level set in mkgmap.
In the Basecamp software the lines shown according to the defined zoom level. That means the XT overrides the set display zoom level.

E.g. 0x1d which is used for administrative border is show ony bellow 8km on the Zumo XT even if I set the zoom level to 14 (which is 200km).

Does anyone know what causes that and if it can be overwritten, or does anyone have information on the topic (which line show bellow which zoom level)?

Cheers,
M
