Parabens pelo forumHello, I'm Portuguese, I do not know how to write very well English.
I have a citroen c3 sx pack installed a new radio but the joystick control next to the steering wheel does not start, is there any way I can connect that to the radio to change wires etc?
Or do I have to buy some special equipment for this?
Here in portugal there is almost no thought I do not find, does anyone help me please?

Congratulations on the forum

Not all radios can connect to the factory stalk controls. You will need an adaptor to connect your new radio to the C3 wiring

Google Translate:
Nem todos os rádios podem se conectar aos controles de haste da fábrica. Você precisará de um adaptador para conectar seu novo rádio à fiação C3.

This is an example of the adaptor you need (click this) to connect a compatible head unit to the Citroen C3 stalk controls fitted at the factory.
