Specs
Pros
Pro Safe projection like hands free heads up display
GPS Navigation & Maps Sygic offers an in app purchase to add on a Heads Up Display for the app. This works for nighttime driving by placing ones device up by the windshield and the device will reflect all information in the windshield for a convenient hands free experience that is on the level of where ones eyes already are.
Cons
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.
Still usable for map viewing though.
