Specs say it can do a2dp with mp3 support and AVRCP. It should work perfectly. The only thing you could complain about is that it is bluetooth 2.0.
It will still enable you to stream internet radio or switch tracks with steering wheel controls and the head unit.
btw I've seen the sprint one in various places; even a third party seller on amazon but its much more expensive. I don't really think sprint made the device. It's probably related to the one on ebay because theres one dude in the world that makes these and he's in china.
I'm probably going to get this and a USA SPEC PA11 ipod thing for my car.
