Using the volume controls on the steering wheel for any headunit !

[XR6-VCT-2000]

Something i came across earlier while having a mess around .
I have recently been looking for a new headunit to replace the indash 6stacker factory unit. After looking around i found alot of the units i was looking at don't support the volume and seek controls on the AU steering wheel.

I ripped my radio out and had a bit of a mess around with the multimeter checking the pinouts on the radio , i came across the pinouts for the volume controls on the steering wheel , these pins adjusted the resistance up and down.

It got me thinking later that / seeing most headunit come with 2 remote controls , u could mount 1 behind the dash and tap into it / tap into the buttons which control the volume, and wire the pinouts from the headunits plug into the remote controls volume control buttons / thus making the wheel change the volume on the extra remote control hidden behind the headunit behind the dash , could wire the remote to power off the car too , so the battery never go flat / or you could buy a blank pcb and copy the remote controls cuircut board and parts / but connect the remotes volume control buttons to the pinouts instead.

I still haven't sorted out the seek button yet , ill see what the go is there and what signal it is sending . As far as the volume controls though , its just using standard resistance (like a pot) to change the volume . Seems pretty easy and standard to set the volume controls up for any headunit , even if it didnt have a remote control , you could pull apart the headunit and wire the pinouts to the buttons or pot on the new headset.

I'll post somemore info on this soon ..cheers
