Outdated City Roads & Messy UI (v2.1)

Bought this app to drive in Portugal & Spain. User interface is very cluttered. The route to follow is too thick of a yellow line; maybe OK for an ipad but difficult to see the road map behind on an iphone. Suggested route in Porto not the optimal with mistakes. City roads for Santiago do not work most of the time; has to use google map find out my location after I was completely lost. The one way street I want to go to in Salamanca is designated as the opposite direction (Google map also has the wrong one way direction marked for this street). So I walked instead of driving within a city. It needs to update those junctions which have removed the Round-Abouts. In Lisbon, it takes me from my downtown hotel to the airport through small roads, including a parking lot, whereas google map suggested a regular main roads route. When inside the cities, I put Navigon in the background so I can still hear the navigation and put Google Map on the screen to see my exact location.
Within a day after I purchase Navigon Europe at $120+tax, it release 2.1, and the price is $8X. This is the most expensive App Ive ever purchased and I regret buying it.
