I had extensive practice with this Sunday (in my PlugIN). Using Entune via the iPhone and the USB port didn't change much for me other than being able to see the Pandora stations on the screen. One thing I did not care for was the NAV speaking her commands WHILE a phone call was in progress. WTF!? How ... annoying! And, every time you tap the voume speaker to turn it off/down, she keeps talking!! If I can listed to my books on Audible by streaming bluetooth, phone talk on Bluetooth, stream the Pandora on the few occasions I use it, why do I need Entune anyway? I guess that's my burning question.
