Love local radio? Then it's time to check out the crystal-clear reception and high-quality sound that HD Radio technology brings to AM and FM broadcasts. Just connect this THD300 tuner to your Clarion receiver, and start enjoying what HD Radio has to offer. On participating stations, you'll hear AM that's as clear as FM, along with FM that's almost CD quality.

This tuner is compatible with Clarion's VZ300, CZ500, and CZ300 receivers. With your iPod® connected, you'll be able to "tag" tunes that catch your ear on HD Radio so you can buy them later at the iTunes store. Many HD Radio stations also broadcast more than one channel on the same frequency. The THD300 tuner allows you to select these additional channels, giving you even more listening choices. Dimensions: 5-1/4"W x 1"H x 3-1/4"D. Warranty: 1 year.

Features

HD Radio: HD Radio technology, where available, offers higher quality sound than conventional analog broadcasts and receives text data. HD Radio provides FM broadcasts that are equal to CD sound quality and AM broadcasts that are as good as analog FM stereo broadcasts. HD Radio also provides a variety of data, including station name, song title, artist name, album name, etc. No subscription fees required.

Note: Right now there are about 2,000 radio stations broadcasting using digital HD Radio technology in the U.S. To find HD Radio stations in your area, visit the HD Radio website (HDRadio.com).

Compatibility: The Clarion THD300 HD Radio Tuner connects to your Clarion HD Radio-ready headunit's HD Radio port. Currently the THD300 is compatible with following Clarion multimedia headunits (as of January 2010).

  • CZ300
  • CZ500
  • VZ300

Multicasting: In addition to conventional broadcasts, with HD Radio broadcasting it is possible to choose from up to 8 multicast programs (HD1 to HD8 and analog). There are also data programs for each program.

Display Information: The THD300 HD Ratio Tuner displays song title, artist and station information on the display of your compatible Clarion HD Radio ready headunit.

Analog Broadcasts: In addition to HD AM/FM stations, the THD300 can also receive conventional analog AM/FM broadcasts.

Presets: The Clarion HD Radio Tuner features 3 FM bands and 1 AM band where you can store your HD and analog AM/FM station presets. You can store 15 stations in each band, giving you a total of 60 HD/analog station presets.

iTunes Tagging: iTunes Tagging allows you to "tag" songs heard on the HD Radio Receiver. Tagging saves the song's title and metadata to a connected iPod (you may store up to 64 tags in the memory). When the iPod is synced to iTunes, a playlist is generated with links to the iTunes Store where the song can be purchased and downloaded.

Note: This function can be operated with the following iPod/iPhone models - iPod nano (3rd/4th/5th/6th gen), iPod classic (80/120/160GB), iPod touch (1st/2nd/3rd/4th gen), and iPhone (2G/3G/3GS/4).

Installation: The THD300 plugs into the HD Radio port on the back of your compatible Clarion HD Radio-ready headunit. The antenna cable from the Clarion headunit is disconnected and plugs into the antenna port on the HD Radio tuner.

Mounting: The Clarion THD300 comes supplied with two metal mounting brackets and mounting hardware to secure the HD Radio tuner in your vehicle.

Connections

Receiver Output: Proprietary 8-pin connector (attached to a 6" pig-tail) with a 40" extension DIN-cable which plugs into the HD Radio input of your compatible Clarion headunit.

Died after only a few months

Written By Inland Guy, Rancho Cucamonga CA on Sunday, October 09, 2011

Crutchfield Customer Review (What's this?)

I thought that the features were great - song title, artist title, ability to tag songs for purchase on Itunes. However, it soon started "sticking" on a station - not changing stations, or taking a really long time to change stations. After a while, it started to change the volume by itself. Once I disconnected it from the receiver, no more problems. I will be contacting Crutchfield to get a replacement

Nice

Crutchfield Customer Review (What's this?)

Got this HD Radio as a free attachment with the Clarion stereo head. Very happy
to have this as it makes the reception and sound so clear. Had a little bit of a
problem fitting it in the back of the unit inside the dash, but with some
re-arranging, it went it fine.

nice

Fantastic! If you live in an area were there is a lot of power lines or large buildings then
this is the add-on for you! We can now hear local stations without all the interference
and fade. Why this option isnt on all stereos already, I'll never know. Don't get any
stereo without this!

HD is NOT Ready

Written By Martymann, Fresno, CA on Sunday, November 28, 2010

Crutchfield Customer Review (What's this?)

Love the clarion deck that I bought this for, but HD radio is not as good as the hype. I
drive all over the state and can only get some limited HD between SF to SanDiego.
When I do get a signal it switches in and out of HD the whole time which is very
annoying when listening to the radio. This may be due to the fair antenna I have on my
98 Honda Civic, I'm not sure. It just seems that it is not really needed on your deck yet.
Wait till they improve it.

Clarion THD300 HD Radio™ Tuner

Crutchfield Customer Review (What's this?)

Radio sounds awesome! iTunes tagging is a really cool features as well. I read
somewhere that you had to run a separate antenna to use HD Radio but I was able to
plug my stock antenna into this unit and plug this into my head unit. Worked great without
any problems!

Use with CZ500

Written By Paul, Omaha, NE on Monday, May 10, 2010

Crutchfield Customer Review (What's this?)

Purchased this with the CZ500. Loving the station that do come in HD. Was a bit
worried do to the fact that it said that "This item does not fit". Called up
Crutchfield and they put my worry at ease. That is only if you hook it up to my
factory radio. I was hooking it to a Clarion radio that could take it. Just a
side note. I got this and both the HD box and radio had a ant. input. You only
need to use the HD one when you hook it up. This is a easy upgrade for any
Clarion radio that can be hooked up to one. Thanks for the Support Crutchfield.
When Time comes around to get a new radio I know where to go.
