It's actually the worse sounding Sat System in any of the 8 cars I've owned. Once my 3 months run out, I won't even keep it even though I have in my other car. It's that bad. The Sat radio sounds remarkably good in my Infiniti (which has a B(L)OSE Audio system no less) though.
Maybe someone will do Bluetooth right, but so far, no one has based on the systems I listened to in the various cars I looked at before going with the M.
