i recorded the noise with my iphone, when the car was simply standing still, engine not running, no wind noise or anything. I'll send it you later, you can hear how annoying it is...Though in the recording it sounds louder that it actually is but still very noticeable to human ears
This is common in amplified systems, the stock amp in your car is amplifying EVERYTHING, not just music. Some people/some cars are more sensitive to this than others so I usually address it on a case by case basis. This goes way back to the early dynavin days and the answer is a simple line output converter installed inline on the speaker wires from the head unit. We used to use the Pac Audio SOEM4 or similar wired (not RCA) LOC. That way you can turn down the signal going to the amp and the noise along with it. Then use the level adjustment on the LOC in conjunction with the head unit to find a happy medium between solid volume levels and low noise.

I havent seen this discussed in conjunction with the Avin yet but the advice and installation is the same regardless of what head unit we are talking about.
