Bro, I've used almost all versions of Sygic for Android since 2013. Maps were more detailed and in-depth in v13-14. Later Sygic didn't update the in-depth maps of Pakistan, only Apk file was updated with some additional features. The area where I live was maped and named in v14 sygic maps. In recent v18 maps, that area is totally absent from the terrain. Moreover some roads and streets are there but those aren't named or if named, named wrongly. So using latest version maps data is of no particular help. I'm still using v14 Sygic.
