Sygic: GPS Navigation and Maps

What's the difference between the standard "Sygic" app and "Sygic & Trakker Nav Pakistan"? I downloaded the standard Sygic app from Play Store, downloaded Pakistan map. Now, when I go into the Sygic folder on the SD card, open the Maps folder, there's a folder named "". I then downloaded maps of a few other countries (the ones with a small size) and there map folder names were like "xxx.xx.2014.09". So are the maps for Pakistan not being updated?
