Well, the TSB about the 4 different SAT receivers suggests the same. It says use the old receivers until out of stock, then continue to use the new receivers. It could very well be that the new cars come by default with the new receivers. And besides Proxus nobody (including me) tried the old Symphony II with the new SAT receiver. Proxus said his didn't work (besides playing the audio from the last selected station). My old XM receiver was software 010, the new one is software 080. And there is also the small chance that his dealer installed some new software, available as part of a TSB we don't know about.
So, is your friend able to change the station and does he see the station info on the screen? Or does he simply hear the audio and didn't try to change the station? It would be interesting to know what part number his Symphony II and his XM tuner was.
