Hi Guys! does anyone have already change their stock head unit with Steering Wheel Audio control, I'm planning to change my head unit of my Toyota altis 1.6V 08', my problem is if I change my car stereo, I don't know if the audio control will still be functional, or should I install any accesories for it to work.

Does anyone know any supplier of Dash Kit/ Audio panel for Altis, because the OEM head unit is like a built in one.
