I think that's baloney and a lie on XM's part. XM is compressing their stations to the point that they are now just above AM quality.
It's no better on my '14 Honda Civic.
But it does sound quite good if you have the streaming service from SIRI/XM. Of course, you'll need a good smartphone and plug it into your BMW (or Bluetooth if if you car has it)
