It worked fine on my way home yesterday. But after reading your post - I realized that the first time I tried I did have the phone plugged in first then unplugged it to try and stream after. Strange bug - but thanks for the heads up.Yup, I use it all the time via Bluetooth. Make sure you go to Bluetooth settings and select the phone or device you're using and click on the "audio music" check box.
I did notice a big though. If you plug in your phone via usb and then unplug it, the car won't reconnect the Bluetooth music. Sometimes it does but I would say 80% of the time it doesn't so you'll have to replug it via the wire. It's the one you plug it in you can't go back type of things. Turning the car off and on is an option too lol.
