Con Updates require running the app
After a Play Store update it is important to run the app once to download all the offline data again, otherwise it will not be usable when no external data is available.
Con Poor map viewing
Sygic's interface is tailored to navigation. While viewing maps in 2D is possible, it populates the map with a bunch of POI icons which detract from street names. The biggest issue is how easy it is to select something or start navigation when zooming in/out.
