There are 3 versions of the satellite radio, XM, Sirius and SiriusXM (otherwise known as SXM 2.0). SXM 2.0 sounds substantially better than the XM or Sirius versions of the radio. There has to be a 2.0 radio in the vehicle to get the SXM signal. Does anyone know which version is in the RDX?

Thanks.

spec sheet on Acura.com says Sirus XM

In one of my current vehicles, there is a SiriusXM head unit and I can tell you it sounds light years better than the prior iteration of either XM or Sirius. I have been a subscriber since XM was first launched. The sound of 2.0 through the top of the line Bose system (for our model) sounds really pretty good. And I’m pretty picky. So I would expect the RDX to have the SXM 2.0 capable radio and that most of the music station should sound decent through the ELS system. Maybe one day they will get even better if they can ever shut down broadcasting for the old XM and Sirius radios. But that will likely not happen anytime soon.
