Smartphone's a nagivation aid that offers convenience, profit

My dad, 50, has been driving his own vehicle for over 20 years now, but a ride to a new destination always used to make him nervous.

Years ago, the preinstalled GPS system in cars was not that accurate. So he would download the city map online, find out the exact coordinates of his destination and understand the surrounding environment.

Yet, he would struggle to find and reach the place as unexpected incidents en route always caught him off guard. For instance, he once spent an hour to drive past a road, parts of which were under repairs. Others would find alternative routes and get past the road in only 10 minutes.
