Have the 2011 Navteq maps but having some problems upgrading from my old 2009 maps. With the 2009 maps there was one file per country map, a basemap and 3 buildings files and a dem file

 

\building\uk.xxx.3dl

\building\uk.xxx.3dc

\building\uk.xxx.petrol.3dl

\map\Basemap_83_2009.09_090930_NIMA_VMAP0.fbl

\map\unitedkingdom_xxx.fbl

\dem\westerneurope.dem

 

With the 2011 map download there are three files per country with different extensions in the /map folder but no updated basemap, no building files and no dem file

Few questions

• Why are there three map files in 2011?
  
• Can I use the 2009 basemap or do I not need one with the 2011 maps?
  
• Can I use the 2009 dem file or do I not need one with the 2011 maps?
  
• Can I use the 2009 building files or do I not need one with the 2011 maps?
  

First of all you can use older buildings files on newer maps, never delete your buildings files. When you find newer ones you can copy them over. Latest buildings files are Q3 2011.

 

You have 3 country files, one is the map, second is lane help en the third is boards above roads. Also you must have something like europe.HNR this wil be the house numbering files.

 

Basemap is important, that is the world map between water en land, you can delete this one but the pioneer doesn't know on cordinates what is land and what is water.

 

I hope this was the answer you looking for !!.
