I see that a number of new apps are now compatible with CarPlay, but I'm not sure how to add them. I have just the original 8 apps when my unit was installed. For example, I have Stitcher on my iPhone, and this is supposedly compatible with CarPlay, but it does not appear on my Pioneer 5000NEX. Same for podcasts. Unless there is a hidden screen or some way to scroll that I don't see (?). Thanks for any tips...
