I have a 2005 (B6) S4 and have been going through a stereo upgrade (morel components, arc amp, alpine processing, ID sub). I'd like to get rid of the antiquated symphony II and go for the symphony II+. The deal breaker is whether or not my current lifetime subscribed sirius module will function with it. Part # is 8EO 035 593, no letters at the end.
Any ideas?

Also, do all of the symphony II+'s have MP3 capability?

Do I use the standard RNS-E harness to adapt this to the B6 chassis? I keep hearing of the wonderful harness' that teddybgame makes with AUX inputs, but it seems he's not manufacturing these anymore.


Thanks everyone,
