I believe the GROM works with the steering wheel controls, but I am not sure. I don't have a smartphone so it does not work for me (only the volume). It displays the song title or phone number on the dash. I can say that it works basically plug-and-play, except you have to run the microphone from the trunk up to the dash (but that was pretty simple).
There are some different models so you may want to see what they each do:
