So I had the choice of making a phone call to activate while I was in the car, or using a website, so I went with the website. But the website wanted me to hit activate while the car was turned on and the radio was tuned and had satellite line of sight and then stay there for 5 minutes. I finally got around to making that all happen at the same time today and lo! Now Sirius works. Cool! I set it to Radio Disney and I'll see what T. thinks of that. He had wanted the Christmas station at Christmas which was the only other time I even seriously tried to make this thing work and we failed.
Minor negatives to Sudbury/Herb Chambers for not making sure this was set up and working when I took delivery. Minor negatives to all participants for sending me confusing mail, but compensating positive to everybody for making the trial last long enough to still have some value in it AND for finally sending me something pithy, clear and useful. If only that had been the first thing I had gotten from them.
