In general, car audio, which is installed at one end of the instrument panel of various vehicles, has been integrated with the control unit and the main body instead of being separable, so that it is used inside the instrument panel to be frequently stolen from thieves during night parking.

This integrated car audio has a wide variety of functions, and the appearance itself is very beautiful and compact high-end type is a frequent theft because it is sold at a very high price.

That is, since the car audio fixed by a few fixing screws in the instrument panel is separated and stolen in a short time by using only a simple removal tool such as a driver, there is an urgent need for preventive measures.

Therefore, in order to meet the above-mentioned demands, removable car audio, which can detach car audio from the instrument panel, has been developed. The removable car audio is connected to the main body of the car audio embedded in the vehicle body. The control unit in charge of the operation function can be detached from each other.When using the car audio, use the control unit in contact with the main body of the car audio.When not in use, separate the car audio from the main body and store it separately in a safe place such as a house. To fundamentally prevent theft.
