I purchased the vivid 10 for my 2015 Subaru Forester with Harman Kardon amplifier without navigation . I notice some white noise(hissing noise) from speakers when you music pause. the noise become even more stronger when It connected to my iphone wifi hot spots. It is like bad radio connection nosie. I have purchased the RCA cable harness as advised by Dasaita Sale. They say the noise will go away. but the problem is still over there.
