As the title states, I am having audio issues when I am playing music from the USB port in my car. Whenever I am playing through USB, there is a really annoying popping/ static sound. I am not very knowledgeable with electrical and audio stuff so some help would be greatly appreciated!

I conducted some test to see where the issue stems from and through the tests, I believe there is an issue with my car's USB port. Using my phone, I tried using two different iPhone cables and the issue still persist. Same thing when I tried using someone else's phone. Afterward, I tried playing the audio via Bluetooth and the audio is perfectly fine.

My car is a 2012 G37s with 70k miles. Audio with USB was working fine until then. Recently, I replaced one of the door speakers and unplugged my heated seat switch for other issues. After doing so, the audio was still fine. It's only until now where I am having issues.

Any ideas? Might end up taking my car to Infiniti sometime this week if I can't fix it. Hopefully, they won't charge me an arm and a leg to diag and possibly fix the issue.

It might be iOS update causing problem try using another USB item or cable on iPhone to test

I sadly do not have access to another USB device but the issue didn't occur earlier. I did not update my phone throughout that time.

Try a thumb drive, play it and see whether the popping is still there. Then you'll be able to tell its actually something to do with the car or your port/cable/phone.

Just tried it and it works perfectly. Tried my old, broken cable again and it started working again. So it turns out to be two faulty cables.... Thanks for the help!!!
