I have a 2000 Toyota Sienna Minivan. I'd like to replace the radio with one that can play MP3 Cds and has an aux input for iPods, etc. Most of the units I see use a DIN mount.

My main concern is that the car has a very nice steering wheel-mounted volume and mode control. I'd like to retain that feature with the new radio, but I don't see any mention of that in any of the online product descriptions at places like BestBuy or Crutchfield.

Anyone know if the steering wheel controls are supported in any aftermarket radios?
