I'm rocking a Sony MEX-BT5000 in my Santa Fe, I've used it with both my previous Mogal and Touch Pro and it's a perfect combination to listen to satellite radio or your mp3 collection through the car speaker system. With turn-by-turn navigation from Telenav it sounds like I have a $1000 in-dash nav-system. It never fails to impress people. lol
