Slow your roll ladies. It still sounds like a JVC (which is not like a Kenwood or /////ALPINE). I bought it to try out the HD Radio not compete for SQ. I installed it yesterday. It has lots of cool features like the ability to only search for HD channels, 7 band EQ, F,R,sub out, you can turn off the internal amp, XM, Sirius, and iPod ready, etc. HD Radio AM sounds better than current FM. When you tune to a channel that also broadcasts in HD, it takes a few seconds for the HD to kick in. On AM music channels like 770, you can really notice the difference. I'll try to describe what it does. When you are watching a movie and the people are listening to a radio in the 40's, they usually make the sound all tinny and muffled. Then, they move the scene to the dance hall where the broadcast is coming from and the music changes to clear full range sound. That is what it does. The difference in FM HD is not as noticeable but there is less static, better highs, and better bass plus the song titles are displayed. Listening to commercial free local radio is kind of cool and most HD2 channels are not in sync with the commercials on the HD1 channel so if 102.1 HD1 is in commercial, I can switch to HD2 and hear "edge" music. Also, for those of you who hate morning talk shows, there is still music being played on the HD2 channels.
Most aftermarket radios have worse tuners than factory radios so the AM and FM reception are weak. This JVC actually has a better tuner than my factory radio and I can pick up 104.1 FM and 96.7 FM although it does struggle to get either HD broadcast. It is a cool new technology and this is the least expensive complete unit I have found. JVC, Alpine, and Kenwood all offer MUCH more expensive alternatives and hopefully Alpine and Kenwood will start shipping their add-on HD Radio tuners soon.
There are 21 HD1 channels and 9 HD2 channels currently (96.3 has HD2 but is not listed in the chart yet. 96.3 HD2 plays "texas" music).
Overall, I am very pleased with the technology and look forward to more offerings from other manufacturers and radio stations.
