You don't have to choose between great sound and your local radio station, since a growing number of your favorite stations now use HD Radio technology to improve their AM and FM broadcasts with better sound quality and static-free reception.

Connect the HDM90 HD Radio tuner to your compatible Dual or Axxera car stereo, tune to a participating station, and discover the difference. You'll enjoy FM that's almost CD quality, and AM that's as clear as traditional FM. Many HD Radio stations also broadcast text information, so you'll be able to see artist info and song titles appearing on the display of your stereo. Even better, HD Radio is free.

Get "tagging"
You can "tag" songs that you hear on an HD Radio broadcast for future purchase. Connect your iPod® to your Dual stereo, and the songs will show up in a playlist called "Tagged". The next time you sync your iPod, you can buy the songs you want from the iTunes Music Store.

In addition to their usual offerings, many HD Radio stations broadcast one or more extra channels, featuring different content. The HDM90 lets you tune in to these "multicast" channels, giving you access to a much greater range of listening choices.

This tuner currently works with Axxera's XDMA7800 and X2DMA500 CD receivers.

  • iTunes tagging
  • dimensions: 5-1/2"W x 7/8"H x 3-9/16"D

Hs radio with dual

Written by: Anonymous from Hayward, CA on December 2, 2012

Crutchfield Customer Review (What's this?)

It was a very easy install with the dual xml8150 head unit. Just plug and play, very straight forward. In terms of the HD quality vs analog, it is great as you get non of the static and it sounds crisp. Another good point is the unit now displays the song info as well as the station. Tagging feature allows me to just bookmark songs I like on the radio and look them up on iTunes.

Here comes the con: if reception is an issue, whether it's the location or using shorty antennas, all the features I just said will not work. Worst part is that the radio will sound fragmented as the stereo switch between analog and Hd radio constantly.

I guess my next project it to get better reception but there isn't much good info on this online...

Lastly, I wish there is an app on my iPod that can use the digital signal from the radio to display album art directly to my iPod when connected to the dock.

Pros: Crisp sound when good signal Tagging function Album and station info

Cons: Reception issue causes fragmented and delayed sounds
