Well a few days ago I got my boyfriends old XM radio and I got rid of the one that I had. He gave me the one that hooks directly into the pioneer radio. I was hooking it up yesterday in a garage and when I took it out in the driveway I found that the XM wants to take over everything. When I put a cd on the cd is in the background but the XM is on with it, and it's louder. I had to call yesterday to have them switch service from one unit to the other and I had to sit on the hold for an hour only to talk to a lady who couldn't speak english. So I wanted to see if anyone knows how I could fix this problem before I call them again. I finally got so mad at it last night that I yanked the fuse out. Also, when it is on I can't seem to control the volume. It has two settings, off, and really loud. So if anyone could help me that would be great, I don't feel like calling India again and talking to a lady who has no idea what's going on. Thanks.
