Ive just fitted a Parrot MKI9200 to my original headunit. One of my friends has just had one fitted, and the guy had tapped it through the headunit cd changer... So he can control the volume off the headunit instead of using the parrots Sh** EQ settings... So his sound quality is as crisp as it was before, being played of CD...
Was wondering if anyone could advise me on what to do and how to do this?
