NCD not work with Navigon 4.1.... only with 4.0... i write this few post ago...
if you want change maps (dont want use original maps from navigon server), you can use Windows Phone Power Tools or Windows Phone Device Manager and extract file filelistBA.xml to PC and edit right size of map file....
- Navigon 4.1 Europe is installed to
- Navigon 4.1 USA
for example for Q2.2012 map file for Germany you change to this in filelistBA.xml
<File URL="Map/Germany.map" Size="238650297" ismap="true" ISO3CountryCode="DEU"/>
save filelistBA.xml and replace existing file on device and send Q2.2012 Germany map to MAP folder
if you want you can also add Brunnel file (tunnel's EU data), upload Brunnel.nfs in data folder
<File URL="Data/Brunnel.nfs" Size="1568428"/>
for Q3.2011 EU speedcams (or any other version), process is same....
add this two lines to filelistBA.xml and upload ALL_HOTSPOTWARNER_EU.pom and HOTSPOTWARNER_EU.nfs files to POI folder...
<File URL="Poi/ALL_HOTSPOTWARNER_EU.pom" Size="813422"/>
<File URL="Poi/HOTSPOTWARNER_EU.nfs" Size="13942"/>
if you dont know how to see exact size of map file, upload first to phone in map folder and see map size in WPPT
