I have HD Radio in my Sky. You end up having the same reception issues as Satellite radio.
When you have a clean signal, the sound is significantly better than normal radio. When you don't have perfect reception, it drops down to an analog signal. The one thing that I noticed around Philadelphia is most radio stations have 1 or 2 HD stations on top of their normal analog station and they do play different music. So it's nice from a variety point of view.
As such, I'm happy with it and it doesn't require a monthly fee, so when it doesn't work, at least I'm not paying for it.
Satellite radio reception is non existent on my work commute. Too many dips and valleys.
Also, with Bluetooth in so many radios's, I have found FREE alternates to satellite radio that I can stream wirelessly from my iPhone to my radio.
Slacker [Free version] and Pandora are my 2 favorites.
This radio, for what you get is a killer deal. I'll be curious to see the review. I am positive the new owner will love it.
