phone or ask in navigation

When I an travelling, I prefer to use my phone to find directions. My phone has GPS, which eans that wherever I am, I can get directions from my current location to any place I want to go to. It's as simple as typing in the location of my destination, followed by pressing a button. Then it's just a matter of following arrows on my phone's screen from one street to another, until eventually I arrive at the target location. This method is much easier than listening to a random person on the street and afterwards trying to remember the directions given to you. Also, it's often the case that the directions are unreliable or just too general to be of any help. Rather than bother passersby, I'll just continue to use my phone and let it be a win-win situation for everyone.
