I have XM in there now but rarely ever use it. I'm paying for something I don't use, so I was thinking about swapping it out, canceling the service and getting HD radio. Anybody ever use it or have it? It's supposed to make FM radio like CD quality, and AM radio like FM quality. Sounds good to me.
It doesn't make the radio CD quality. It's still radio, HD= Hybrid Digital, not High Def. After the digital locks on (takes a few seconds), it might be a LITTLE crisper sounding, but nothing major unless you had a really high end audio system.
