I have just fitted a new head unit in my S60, replacing the volvo head, but using a PC9-414 lead to still use the dolby amp...The unit is all working, but there is a whistling noise coming through the speakers when I accelerate..
It does this on radio, usb, and also dvd, and not sure what i need to do to stop it, as its doing my head in!! Is it an easy fix to stop this, or should I just put the original head unit back in? Or is there an easy way to get mp3 compatability in the S60 (2001) and I think the head is a 803?

whistling like that is usually a poor earth, might be worth giving the head unit it's own earth rather than trusting the one that comes through the loom...

doesn't an IMIV work with the HU-803 for mp3/ipod compatibility?
