My wife and I have been waging a war with the Prius C2 we bought, but I finally won out by deleting her phone from the bluetooth saved phone settings until I could figure out a fix to this. By default, now that my phone and stereo are paired, if I either stream from Pandora or the ipod app, once it is paired to the car it outputs bluetooth to the speaker. This is great because all audio to include the phone features work. I've noticed that when I connect my phone to the USB input of the car via the standard 32 pin apple charging cable, the system gets all problematic because the music app on the phone is set to default output via the bluetooth rather than the dock connector. This drove me crazy because any phone paired within range will automatically start streaming from where it left off while in bluetooth mode, and I couldn't figure out why my phone wasn't being utilized. There are no settings for elevating the output source in the iPhone settings to force dock connection to win vs bluetooth, and I believe this is a bluetooth issue. Does anybody else notice this? I could just manually force the phone to output via dock connector upon every reconnection, but it seems stupid to even plug it in now because once I sit in the car and turn it on, within 5 seconds the bluetooth is already streaming so I'm now just using a cigarette adapter to charge the phone while the bluetooth works... It just seems odd that there seems to be competition for audio out between the usb interface vs bluetooth and I don't know if the issue is my phone or the stereo. Any ideas would be appreciated.
