I'm excited for this if it's true. Since day 1 over 4 months ago, every time I start the car for the first time of the day, if it was left on an FM radio favorite, it will start up with one of my TuneIn streaming favorites. If left on a TuneIn favorite, it would jump to another TuneIn favorite. Interesting, if left on a Slacker favorite, it always stays the same.
Then there's the great bug where all the streaming favorites will just completely disappear for no reason every once in a while. I hope this update gets the media player working correctly.
