Yes, constantly. Google Maps is invaluable; I use it daily in Canada. It's usually accurate, providing multiple route options. However, it occasionally fails—outdated information, wrong turn recommendations, poor coverage areas. In Vietnam, maps sometimes lacked detail for rural regions. GPS sometimes loses signal in urban canyons with tall buildings. The app works well for orientation, but requires battery power. I've gotten lost following GPS errors—trusting technology blindly is risky. I've learned to verify with landmarks. Overall, navigation apps have transformed getting lost from frustrating to manageable.
