I'm in the process of installing a new JVC head unit that I got from Crutchfield. Everything works except the radio. They sent the antenna adapter which I used but I am unable to get any AM of FM radio broadcasts. I noticed one of the wires on the plug is for a power antenna but I've tried it with and without this wire hooked up to the harness and neither works. Has anyone else had this problem?

 

Nevermind. I had the antenna hooked up the the rear aux in. Hooray for pictures in instruction manuals... All is well.
