I bought Prius v Two model (instead of Three and Five) to escape from crappy Entune system. I have an Apple iPhone 4S (actually two of them). My basic use cases: TomTom navigation in iPhone and 30/70 music/no music during my drive. Here is what I have now: 1. Bluetooth connection works fine, but it will drop a couple of seconds from each navigation direction in case if your iPhone's music player is on pause (there is no active Bluetooth stream). My friend have the same issue with his Subaru Outback. 2. To avoid having issue above you need to use cable to connect your iPhone to standard USB jack on Prius. This also will give you a charge on long trips. 3. There is no way to select a specific album/podcast/genre/etc while utilizing Bluetooth connection for audio player. You simply don't have Browse and Songs buttons. Your entire iPhone's audio library will be available for playing, but you will not be able to navigate through it. You can't also navigate using your standard iPhone's Music app, it will show you a screen with "Accessory connected" message. 4. Car starts playing a music EACH time when it see your phone over cable or Bluetooth. You don't have an option to turn it off in Setup/Settings of Prius v. I hate Toyota engineers and managers for that decision. Pause button is my best friend. It will choose first song each time on your entire sorted library. It's "Abracadabra" in my case. 5. Trick to get phone's cable connection (iPod) working: connect your iPhone ONLY AFTER starting your car AND when Bluetooth Audio Player will connect to your phone. If you connect your iPhone and then start your car than iPhone will see cable connection first and after couple of seconds car will connect to it over Bluetooth but that doesn't switch your audio input from iPod to BT on audio system! You need to select BT source in car or start iPhone's Music app and select "Dock connector" output instead of "CAR MULTIMEDIA". Changing connection policy from "From Vehicle" to "Audio player" doesn't resolve that issue. 6. You can't selectively disable BT profiles netheir in iPhone or in Prius v. In other words: your iPhone can be connected as whole (phone + audio player) over Bluetooth or can't be connected at all. 7. While connected on cable (iPod connection) you can Browse your iPhone like any iPod and enjoy nice artwork from your songs. 8. Siri will work, but there is no way to activate it from Prius v side. You need to press a button on iPhone itself. 9. There is no international characters support at all: all non-latin symbols will be replaced by star characters. Hope that it will help others to choose on Entune/non-Entune option.
