I've recently started hearing static popping noise coming from the speaker whenever I listen to any music from my Iphone. When I put on radio it plays perfectly fine with no static pops. Any reason why it is doing this?

Bump: Still having this problem

 

Pulled this from another auto forum, might help you.

Try these troubleshooting tips to help correct your USB connection’s static playback:

Check your device for programs running in the background that may be causing audio interruptions.
Make sure that your original audio file is a high-quality version. Issues with corrupted or low-quality files may become more apparent at higher volumes.

Inspect your USB cord for damage, and be sure that it’s firmly plugged into your vehicle and device. (Note: You may want to try using a new OEM USB cable that’s sold or compatible with your device.)

Ensure your device’s volume isn’t set too low. A low volume setting on your device, combined with a high volume setting on your vehicle, may over-amplify the device’s audio signal, resulting in decreased audio quality.

Your device may be retaining a static charge due to a grounding issue.
Consider using a USB cable with a ground loop isolator to minimize noise from static and other electrical systems.

The static could also be caused by electromagnetic interference from other electrical systems, in which case a shielded USB cable may help resolve the issue.
Connecting your device over USB will most likely yield better sound quality than connecting over Audio line in.


Just a thought, you could try using another IPhone to see if the problem is still there.
