Hello.
I just got my Bluestar and installed in my 2005 Suburban. The functions seem to work beautifully and the call quality on my end inside the truck is amazing. However, the person I am calling gets a high pitch noise in their earpiece, much like feedback. It does this whether I am placing the call or receiving the call and sometimes it is constant for the length of the call or intermittent. Again, my side of the call is crystal clear.
Any ideas?
