Alfa 156 gta connect nav installation

Hi,

I have 2003 156 GTA SS and standart Blaupunkt Radio CD. I want to change this Radio CD with original Alfa 156 RNS4 navigation. I already have. But when this implemented, steering wheel buttons did not work. When I look at the e per, I realized that an adapter required which code is 60678515. But switch of this adapter seems as not same with back of navigator. Should I get more items to work navigator properly? and what are they?

Thanks

Murat

Hi,

According to search in this forum, I understand that I need an adapter for steering wheels buttons work properly. And the code of this I got it. But this adapter has only one plug. According to info from this forum, this adapter is interface between r 3 wires system for standard unit and 2 wires system for navigation radio unit. In my car, green adapter is used for steering wheel control an it connects to directly standard radio cd unit. But How can I connect this adapter, head unit and wires from steering wheel (green adapter).

Regards

Murat
