I just installed the headunit. The cd/mp3 works fine, the music sounds fine but the radio doesn't work too well. I get some FM channels and one or two am channels. I double checked that the antenna was connected. Any ideas what might be wrong?

 

Have you checked that the plug is all the way in? Also that you didn't disconnect the antenna from the HU's ground.

 

Here's the problem.
