Entertainment systems change. Technology changes. Music and video sources change. If you still have the same factory-installed head unit�and can't replace it because it's integrated into the vehicle's electronics�how can you upgrade your system? VehicleHub™ Pro has the perfect solution. You can keep your current head unit,yet add all the media sources you want, build up your sound�even to 5.1-channel�and enjoy convenient central control with our new ORB controller. It's a definite change for the better.
