I was looking forward to trying out "HD" radio in my new Genny but the results have been very disappointing in both signal quality and content.
I live in the Phoenix metro area which is generally flat and without a lot of tall buildings. Nevertheless, the HD signal in my Genny has frequent drop-outs as I drive around. Most seem to happen around intersections where taller buildings exist but these buildings seldom exceed four stories.
I haven't driven significant miles out of the metro area yet so don't know what the range might be compared to analog FM (which can be close to 100 miles in the case of KOOL-FM towards Tucson). Reports from others have pointed out that the range of an FM-HD signal is substantially shorter than analog FM.
The other very disappointing thing is HD content. Here in the Valley the primary FM signal is the station's format. Oldies, CHR, Talk, Sports, Alternative etc. The HD sub usually carries another totally different format - there are no simulcasts I am aware of. One of our FM's is continuous Christmas right now and is one of the best FM signals here. Their HD-2 signal is supposed to be Oldies/Classics but I can almost never hear them. The signal is dead. Another is Classic Hits with 70's Oldies as HD but they are playing music now that sounds like early 50's R&B.
HD AM radio has been harshly criticized on many forums for adjacent channel splatter where it makes neighboring frequencies unlistenable. Since there is nothing on AM in my market I listen to I did not test the AM side. Since a great many of these AM-HD stations are dropping their HD capability because of this interference it is a declining listener base anyway.
I am of the *ahem* older generation and my hearing isn't what it once was. Nevertheless, HD, when it is working does not sound any different than analog FM. My opinion has been confirmed by a friend who actually measured several HD signals and found that, although a digital signal is supposedly capable of higher frequencies than analog it never measured higher than the normal 15KHz of analog FM. So much for improved audio.
So, even if HD radio was a significant audio improvement over analog the lack of content, at least here in the Valley, makes it uninteresting to me. Fortunately, there is an app which makes possible creating audio-DVD's (not DVD-Audio) of my library to play in the CD changer or I can dump my mp3 library to the flash stick and play through the USB port.
If any Hyundai engineers are reading these forums I would strongly suggest dumping HD radio and saving the iBiquity licensing fees and the aggravation which some dealerships will suffer when vehicles are returned because HD radio does not work as advertised.
