Thought I'd pass on an option about the power hook up for the Starmate Replay. I have mine connected to a constant power. Originally, I wanted it to shut off when I turned the radio off or when I exited the vehicle after turning off the iginition.

However, one good thing about my present set-up is that the record function still works at least until the autoshutdown feature kicks in after one hour. That way if your listening to a talk show and you stop for lunch or whatever, you can pick up what you missed.

If you have it connected up to shut with the radio, you lose what you had recorded so says Sirius program support.
