Satellite radio on new BMW's and MB's in Sirius trouble?

If you own a new Mercedes or BMW with the navigation system and you want to add Sirius satellite radio to them, expect a long wait...

Sources tell the Spies that it will be AT LEAST September before compatible units are available.

The nastier rumor that's being speculated on from high level sources in both companies is that it may NEVER show up.

The people we spoke with said they are having compatibility with the MOST bus used in these autos.

Don't expect XM to come to the rescue either...we hear in their testing, the same issues are haunting their engineers...
