System Operation
The Televis ion s ys tem has various l evels of us er cont rol t hrough the Touch-s creen, ICP (int egrated control panel) and
s teeri ng wheel control panel. The s ys tem includes nine analogue and nine di git al cha nnel pre-s et s . As wit h t he audio

The Televis ion s ys tem is primaril y cont rol led from the Touch-s creen and t he ICP (i nt egrat ed cont rol panel ) which are
located i n t he cent er of the i nst rument panel. Control s i gnals from t he Touch-screen di s pl ay are sent on t he MOST (media
