MJ777LR,
Did you ever get a new factory head unit? I am about to do this upgrade and am afraid of the same issue; OEM hiss that was there before is now exceedingly worse. My car is still under warranty, so I could have the dealership address the hissing noise. And I may do that, but wanted to know if you had success yet with locating something else.
