Metra 40-HD30

Good product and not difficult to hook up. Money well spent!

Fits perfectly in 2009 Honda CR-V

I used this to add a HD radio receiver's antenna to the existing FM/AM antenna system. Rather than using the FM modulator, I used the HD receiver's output to plug directly into the factory supplied input jack. The antenna splice was simple--unplug the short and long factory cables under the right side dash and plug in the respective metra cables.
