A vehicle media system for use in conjunction with a portable media device is set forth. The mains bridge includes a controlled mains bridge for rectification of the mains voltage to produce a DC intermediate-circuit direct voltage consisting of arms conducting during the positive and negative half cycles of the phase voltage of each phase of the supply network, each arm having a switch unit formed by a diode and a power semiconductor switch, e. The solvent-borne coating compositions containing the rheology control agent have improved rheology control on application and are useful for OEM, refinishing or repainting the exterior of automobile and truck bodies and parts thereof.
