Im managed to use my steering wheel buttons to control volume up-down, track selection etc using centrafuse. the ibus interface is a chepo one in the ebay tht i bought. Not resler. the software i use to interpret the steeringwheel key press is ibuscomm. it will broadcast the equivalent keypress to centrafuse for controls. so if ur using centrafuse as the incar entertainment interface, ur steering wheel buttons is still functional. u need to map the proper hotkeys in centrafuse and assign it to ibuscomm. a huge move forward for my incar pc proj :top:
