Car Audio - steering wheel control buttons?

Currently, I have a CD player / radio tuner in my Mini Cooper. I can control the CD player, radio, and volume from the steering wheel buttons.





If I change the Audio unit so that it has an auxillary input for an mp3 or Ipod player, does anyone know if the steering wheel buttons can still be used with a new car stereo? Thanks.Car Audio - steering wheel control buttons?
Depending on the model of radio you buy,you can use one of these.
