Yes, "Sat Ready" is a little misleading, I have covered this before.
When we were the only ones buying this radio we had them take the "sat ready" print off of the radio and we disabled the button. Now that other mfg's use it, they wanted it in there.
"Sat Ready" as you now know, just means you can control the tuner through the radio, with no additional "controller" needed. Of course you still need the antenna & receiver/tuner. It's sort of similar I guess to Satellite TV, where we provide a king dome dish...and you still need to provide the tuner.
I agree however, I connect via Bluetooth (Alas, my iPhone 5 has the new cable) and just stream music. I plug in via USB to charge.
