I am curious what after market stereos work with the steering wheel controls and is there a code or something on the stereo that you can look at to figure it out or do you have to buy something extra to get them one to work. Also what options do you lose with an after market unit.

Anything aftermarket stereo with infared inputs can be adapted to the steering wheel controls.


Your going to need something like this
