A:Answer Yes, you can get an adapter for the steering wheel controls to work properly.
This unit has it's own built-in bluetooth, so there is no reason to get an adapter for it.
You can plug any old Lightning cable right into this unit's USB port, so besides the cable, no adapter is needed.
You will probably need to get a different satellite radio tuner though, as I doubt the factory one in your car would work with this unit.
