I do have it running with a working scale on my Android tablet, using a customized NAVIT.XML.
The command should be this one:
Code:
<osd type="scale" x="0" y="150" w="400" h="50" font_size="300" enabled="yes" />
The entire section:
Code:
<!-- osd items allow to position display and control items directly on top of the map: -->
<osd type="compass" enabled="yes" x="-160" y="-212" w="160" h="212" font_size="532" osd_configuration="1"/>
<osd type="text" label="${navigation.item.destination_length[named]}\n${navigation.item.destination_time[arrival]}" x="-160" y="0" w="160" h="106" font_size="600" osd_configuration="1"/>
<osd type="navigation_next_turn" x="0" y="-107" w="130" h="80" icon_src="%s_wh_64_64.png" osd_configuration="1"/>
<osd type="text" label="${navigation.item[1].length[named]}" x="0" y="-27" w="130" h="27" font_size="366" osd_configuration="1"/>
<osd type="button" src="gui_zoom_in_64_64.png" command="zoom_in()" x="0" y="0" osd_configuration="1"/>
<osd type="button" src="gui_zoom_out_64_64.png" command="zoom_out()" x="0" y="75" osd_configuration="1"/>
<osd type="button" src="cursor_64_64.png" command="follow=0;set_center_cursor()" x="-80" y="150" enable_expression="follow>1"/>
<osd type="scale" x="0" y="150" w="400" h="50" font_size="300" enabled="yes" />
<!-- Currently on ROADNAME -->
<osd type="text" label="Strasse: ${navigation.item.street_name_systematic}" x="100" y="0" w="450" h="50" font_size="300" enabled="yes"/>
<osd enabled="no" type="compass"/>
<osd enabled="yes" type="text" label="${vehicle.position_speed}" x="140" y="-107" w="400" h="107" font_size="1000" osd_configuration="1"/>
