[color="red"]Does the fact that I don't have these other files cause any problems?[/color] Can I mix and match Navteq maps and the other files from the tela-atlas bundle? It doesn't sound safe, but worth asking.
[color="red"]No, No problems will occur.[/color] You will just be missing a few advanced 3D View effects without Building and DEM files. As a result, your system may run a bit faster than those that do. ;-)
FDA files are Driver Alert ("Railroad crossing ahead", "No left turn", etc) files strictly for Navteq Maps and for use with TTS Voices. Without them, you just won't get such alerts.
Phoneme files are regional dialect 'helper' files for TTS pronunciation. You will probably never miss them.
I have read that POI files can be mixed together (Navteq and Teleatlas/TomTom) in the same folder, but I personally do not do this, nor have I tried.
In
general, other types of files should not be mixed as they are map specific. Never mix Navteq Map files with Teleatlas Map files for the same region in the same folder. Bad things will happen.
If you want to be able to use both Navteq and Teleatlas/TomTom maps, and choose between them (also optionally switching POI files at the same time), then you need to install and configure a MapChanger utility like one that comes with various skins.
