I have found that three or less satellite 'connections' cause the symptoms you describe, Snowball. The only time mine has been a waste of space was when I foolishly used it to try to drive to a Reunion in London. Being surrounded by tall buildings really messed it up. Because of parking restrictions in the area I was going to, i got a friend to drive my car home on the understanding he would collect me afterward. By some quirk of fate, he actually knew where I was heading, and took over navigation.
