Assume yours is quadlock then?
56> CTSST001 this one is more expensive as it uses the CAN-BUS system in the vehicle to convert the signals required for the radio to respond to the stalks rather than the old system that was k-bus
however if yours is a late registered model then youll need the first i suggested
best way to know is if your wiring is this-ST001 required
or this-ST002 required
The patch lead plugs into the back of the clarion radio,the other end of the patch plugs into the above part,this then plugs inline between your radio wiring loom and your radio wiring loom
