To prevent expensive options disposed on an on-vehicle audio installation box panel such as an embedded car TV-unit, an embedded car navigation system or an embedded car stereo from being easily recognized from the outside of a vehicle; and to reduce possibility of damage of the theft.

The on-vehicle audio control panel anti-theft cover is arranged on an exposed part such as a control panel disposed on an on-vehicle audio installation box panel such as the expensive embedded car TV-unit, the embedded car navigation system or the embedded car stereo so as to cover it. The on-vehicle audio control panel anti-theft cover comprises an on-vehicle audio control panel cover base 2 as shown in Fig. 1, a dummy control panel 3 such as a cassette type car stereo, MD type car stereo or CD type car stereo which is a general and not an expensive model, and a dummy cover 4.
