You still need to connect it into the MOST ring. Integration of after-market units isn't easy (but can be done), there are other posts on this subject. If you are looking for cheap, just use an FM modulator as per post #2, such as iTrip etc.

 

I ran for almost 2 years with FM Modulators for both ipod and satellite, works ok and less that $50

 

Which ones do you like best?
