I have a Opel Vectra 2.0 DTI year 2004.
Inside was a siemens ncdr 1100 navigation with cid display. Since navi was broken I have bought Sony head unit I think model is BT2900.
It works perfect , but there are two problems. I cant use steering wheel controls to control either sony or my board computer. Before , while siemens ncdr 1100 was installed in car I was able to use steering wheel controls to control board computer. This is the thing that I need now , controlling Sony head unit is not so important.
Is there any adapter , kit or device that could enable me to control things displayed on my cid by use of steering wheel controls ? For example switch to board computer mode , acknowledge warning that is displayed on cid and etc.
Any suggestion is appreciated .
