Never been able to get satellite signal

Question

I never could get a satellite signal so I took it to a installer and he couldn't get a signal either. He tried for 20 minutes and nothing happened. A map appears on the screen but it's not my area and it says it's searching...... I called the toll free number listed in the instruction book and it was disconnected. I've wrote an e-mail to the address given in the book and it's never been answered.
