2012 Prius 3/Solar roof. FYI iPhone4 will not do internet access via Bluetooth, only if it is plugged in via USB port. Android and Blackberry phones can do internet via Bluetooth. That's an Apple crippling the iPhone issue not a Toyota issue. Problem is the Toyota USB port is underpowered and my iPhone case which includes a booster battery (Mophie and CaseLogic make them) gets an error from the Prius "USB using too much power will turn off" and it shuts off the USB access. My Ford Escape Hybrid USB had no such problem. Would this be a setting in the Prius computer that could be programmed to accept the iPhone battery case power draw? These are all to computer USB voltage/amperage standards so it is purely a Toyota issue in underpowering the USB port below industry standards.
