I am looking around for a new HU. I don't need/want navi on it. I get that on my iPhone. I want it to have good bluetooth calling. Bluetooth audio streaming would be nice but aux is just fine too. Don't want to go over $500. I want it to have sirius Xm. Would prefer a **** for volume control. If you purchase it on amazon it seems like the Sony XAV-601BT does all of this. It is newly released and there is not much reviews out there on it. So I was wondering if anyone has had any experience with it. I have the bose sound system and an iPhone 4s
