For anyone wishing to upgrade their factory fit head unit to a Pioneer head unit and still keep their existing steering control then the perfect solution is a Pioneer steering control
These interfaces fit between the existing vehicle wiring and the new Pioneer head unit.
The Pioneer range of steering controls are 'plug and play' which means that they are quick and easy to install, of course each interface comes with a wiring diagram and instructions.
Pioneer steering interfaces are available for a wide range of vehicles.
