Changer is probably a standard Blaupunkt CDC-A08, despite confusing description. Contact marked * are not always connected. The radio is connected with the installation of the car using the CAN bus. Some radios are additionally secured control of the CAN modules are connected, if it does not detect the display will show the message CANCHECK. This is a very effective protection against the use of another's property, but it turns out that it is no longer a problem to bypass the blockade.
