GPS Tracking Device

My uncle is spending his first New Year in the US.  And since it's his first, he is getting a lot of invites from all our relatives there.  Too many I'm not even sure if he can see them all before he returns here in Manila.  My brother lets him use his car and says, uncle is enjoying going places.   He's only seen some of our relatives and he's fully booked until the rest of his stay. My brother assured mom that he'll never get lost because the car is equipped with a gps tracking device.  Right now our uncle is staying with my aunt in Flushing, NY, and will be back in Connecticut the day after New Year.
