I decided to try the new bluetooth dock for SiriusXM radios and it works great (out of stock at the moment though). It's a good option for those without the AUX port, but the only downside (well, maybe two) is it only works with certain radios (Onyx series) and it does not display artist/song/station on the head unit itself. But if you're looking to add SiriusXM to your car this is certainly an option.
