Pioneer AVH-X3700BHS Not playing HD Radio?

So I just installed the Pioneer avh-x3700 and so far everything seems to work perfect… Except the radio. I can play music through my iPhone fine and the amp I have it connected to turns on, but when I go to HD Radio it doesn't play the songs. I can change the station and even see what song IS playing, but there's no sound? I'm totally at a loss here, normally I get these things figured out after a while but everything I have tried isn't working. I guess some other details are its a 350z and I'm using a wiring harness to set it up, I used all the wires that came with the harness except a few that really don't matter (Parking Brake wire, Reverse gear wire, Illumination wire… Ect) and then one that I'm not sure weather its causing my problems or not, a blue wire that says its the power antenna? Its literally the only thing I can think of thats causing this problem, I don't have a all blue wire to connect it too so I'm not sure what to do with it. I tried connecting it with both my remote control wires, the blue with a white stripe, but still no difference. I unplugged everything multiple times and reconnected it, and I even put the old one back in for a sec to make sure it wasn't something to do with my car or stock wires. I have messed with literally all the settings I could find on the head unit and nothing works… Any help would be amazing! Also sorry for such a long post, I didn't want to get bombarded with questions about details after I posted this.

Let's begin with simple things. Go to the AV SOURCE SELECTION SCREEN, touch RADIO SETTINGS select HD Radio. Be sure it has been turned on. It may have a factory default of "off". Also be sure the volume has been turned up on the Audio Mix menu if you are using it in either AppRadio or MirriorLink mode. There's also a mute/unmute button there. If that doesn't help. READ the user manual before you assume it isn't your lack of knowledge about the X3700.
