There isn’t much that this is supposed to do other than give HD radio and it seems to be working like a champ.
I had this wired in to my JVC KD-AVX77.
I wish I could rate HD radio in general, though. It’s all hype with little substance. If you’re deciding between buying the HD radio kit or adding an amp or getting a higher end deck, go with the other options. Only add this if you have a lot of cash and just want to blow it on something to say, “Hey, I have HD radio!”
I have this connected to a kw-avx820. This unit actually improved my non HD reception and the HD unit works great.
Especially on AM radio, there is a huge difference between HD and standard AM. FM saw a boost as well. I would even dare to say the quality is better than satellite. The only catch is whether or not your city has HD radio and the terrain you have to travel. Bridges and downtown makes the signal stop and start which can be annoying, but depending on the station, switching can be seamless. Some radio stations have a very slight delay in the HD broadcast that results in an echo-like occurrence when switching. Other stations just switch without missing anything.
These issues are not the problem of the device as much as they are the nature of current HD Radio offerings. It can only get better.
One suggested improvement for JVC on this is to have a larger buffer to avoid skipping when going under bridges. If I am way-speeding, it may not happen, but at any normal speeds it will drop HD to standard, then take about 5 seconds or more to get back to HD.
Once the HD Radio bugs are worked out with the stations, this will be even better. The quality is tops when you can get a great signal though.
This add-on HD tuner was very easy to install, as long as you are comfortable with removing the stereo from the dash. Just requires a power source and plugs into the back of your JVC stereo. HD makes good FM stations sound even better but it really shines on the AM band. The best part is the fact that stations that broadcast in HD usually have a second broadcast station with different programming, so you have even more choices.
