No GPS, poor data – NAVIGON Mexico Review

Very unsatisfied with this expensive app. I got it for a trip to Cancun and south. Never got GPS location ( I assume it needed cell phone signal which was turned off to avoid charges.) the FAQ suggestion to totally reinstall the iPhone to get better reception is ridiculous. "POI" Data about restaurants etc was sparse unless you were looking for a Subway sandwich. You are better off buying a map.
