Query: Buyer beware

Don't buy this product, it's junk! The dock simply doesn't work. The wires and antenna are fine (which I know because I used them to hook my car dock up to my indoor stereo system) but the dock is dead.After many frustrating hours trying to make this system work, we gave up. I have returned this worthless junk and we will do without Sirius in the house.
