I have XM currently in my car and i have a wayyyyyyyyyyyy smaller unit that the Delphi, granted its not mobile like the delphi, but its XM...
I think it goes by the name XM Commander made by Terk
Its nice, its small and I happen to enjoy XM...never the same stuff, lots of different stuff. I dont see how Stern going to Sirius is gonna make a difference, he still sucks lately.....
