Got an xm 5800 the other day and thought that it might be fun to plug it into the telly, so I used an AV-cable to plug it into my TV and I picked "Tv-cable" (Or whatever it is) on the little menu that popped up. But only a heavily disordered picture without sound shows on the tv, and a little message shows on the phone's screen saying something about the tv being non-compatible. Anyone who knows anything, please tell me that little you know of. Help is always appreciated no matter how small it is!
