technologically challenged

I just bought a 2013 Outback with a navigation system that cannot bring me home, to church or to a restaurant.. Everything works as far as display and voice etc, street name and route numbers but the device takes me right past my house and everyplace else that I want to do to. It takes me to the general location and then apparently leaves it up to me to get specific. Is it broken? does it need to be replaced? Others in the forum do not report problems. Thanks
