Here's the problem: Sirius Satellite radio looks like a better deal for me, but the tuners seem clunky compared to those for XM (Delphi is nice and small).

Now, there is a new Sirius unit (Clarion SIRPNP) that closely resembles the Delphi, but it isn't available in all the usual outlets where I can play with it (Circuit City, etc.)

Has anyone out there bought one? How well does the FM Modulation unit seem to work (compared to inserting a cassette, which just adds more wires)?

The car base-unit looks pretty large.. but perhaps I could mount it on the side of the console -like in the one in the other post with the great pictures. (W124, 300D).

SAds for the other Sirius units available, the Audiovox is, well, Audiovox -and is a brick; the JVC I can't see anywhere.

How many potential Sirius subscribers go with XM instead because the tuners for XM are all over the place? Wake up Sirius! Push (pay?) equipment manufacturers to design a Sirius unit that I can put in my Benz! And no, I don't need a whole new head unit -just the add-on.
