Hello MB Community!

I got a 2002 Mercedes Kompressor S w203 and I've decided to swap my factory radio to a double din. I've brought an Ouku Free Kudos Map in 4GB Memory Card and I've managed to connect all the stereo wiring and voltage but I can't seem to find the steering wheel buttons wiring to connect it to my new radio. Any suggestions?

Link to the radio:

The audio wirings and V12/ACC and Ground(what I've managed to put together) and some more leftover wirings I have no idea what they are:


The set of cables was cut off from the longest plugin (the top) and I'm not sure if they're any use to me (I can't seem to figure out what AUX in and out mean)


These are the steering wheel wiring coming out of the radio:


Any help is appreciated!

Anyone please?

The w203 uses a can bus system to work the steering wheel controls. You need to purchase a Metra Axxes like this
