Waste of money
Zero stars. Total p.o.s. and big waste of time and money. No map shows up, just nav buttons so I bought ripoff in-app map for $4.99. Nothing. Link to developer site does not work either. Will report to Apple.
Broken Map
The map breaks up with enlargement. Really bad feature with mismatched overlay of streets. Will test it on my next trip to see if it works as a standalone without WiFi.
