Best Buy told me it needs a VGA connection. Now it's making sense since he just installed a 5000NEX in his car, so maybe he got confused with ports on different models of the NEX.
So for AppRadio mode (also for the record I can't seem to stream music via Bluetooth, only via iPod1), I can't stream and charge simultaneously? I have an iPhone 5s.
One other thing: when I turn on the car, a Nissan Altima Coupe, the radio turns on but gives me an error message. Something like "unable to detect auto connection, retry?" Can't fix. Thanks for the help.
