If youre considering downloading Stitcher to use with CarPlay, dont bother. About half of the time, Stitcher hangs in CarPlay with a "Stitcher is launching..." Message that never goes away. If youre lucky enough to get it to start up, resuming a podcast never works. Youll get to the play screen and the play button wont function. Looking at the phone, it will say "buffering". If thats the case, that feedback should be presented in get CarPlay interface as well. Anyway, the buffering doesnt go away until you quit the app, restart it and then use the phone interface to play the podcast.
