For those who's fade up with the slow 3G connection, especially when streaming music from Rdio. They can try connecting a pocket wi-fi. I connected my pocket wi-fi and works perfectly with instant streaming. I have it connect to the cigarette 12v socket and it comes on automatically when the car is on and the unit goes into sleep mode when the car is off. Now I don't have the buffering problem with 3G. I don't have the navigation 6.2 yet but I'm sure this will help the navigation streaming too. Hope this is helpful.
