Simplest solution is to get a separate power adapter that plugs into the cigarette style power port, then plug your smartphone into there. Use a different colored cable for the USB port (i steal one of my daughter's rainbow loom bands, but colored electrical tape will work too) so you can choose when you just want to charge and when you want USB phone integration.
I wish the gen 1 would automatically find my phone and start playing Bluetooth from where I last left off. No, I have to hit the button on the steering wheel every time to cycle through the options to get to Bluetooth, and only after waiting 30 seconds or so after starting the car.
Another option is to plug something into the AUX port so the car senses the cable, then use AUX as your main audio source selection. Bluetooth will still pair for phone calls, but with your default audio set to AUX, and with nothing plugged into the other end of that cable there's no music, only silence.
