If you're one of the folks who've bought the audio streaming kit that's on eBay (2010 and 2011 Priuses), would you check in here to let us know how reliable it's been for you so far? I've got a 2011 with package III and an iPhone 5 and I'm trying to decide between this $35 kit and a full on head unit upgrade. Quite a price difference! The reason I'm asking is that traditionally these car plug-in bluetooth devices seem to have a limited lifespan. Are you finding that the device is still behaving well with your built-in Bluetooth (JBL systems) for phone calls? Thanks for taking a moment to read this.
