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
ori ent ed s yst ems t rans port ) ri ng to the Televis i on tuner. The Televis i on tuner uses a dedi cat ed CVBS (compos it e video
s ignal) bus t o t ransmit video s i gnals to the Touch-s creen.
Control s i gnals from t he ICP (Integrat ed control panel) are rel ayed on the medi um s peed CAN bus t o t he ICM (i nformati on
