Removing
Switch off the ignition.
Disconnect the negative cable from the battery.
Attention: This will erase the data of the memory blocks in the radio and in the electronic engine control units. This prevents unauthorized turning on the radio after connecting the wires. The voltage supply is interrupted, for example, when the wires from the battery are disconnected, when the radio is removed or when its fuse blows.
You must write down or memorize the security codes before disconnecting the wires from the battery or before removing the radio. If the code is unknown, then the radio can only be turned on again in the workshop.
The code number of a specific radio is given in the design for its operation. It should not be taken with you in the car.
Insert the removal brackets into the front of the receiver as shown.
Press the removal brackets to the left and right of the radio (1) and at the same time pull the radio together with the brackets from the front panel (2).
Disconnect multi-pin plug and antenna plug (arrow left).
Attention: When doing this, pull on the plug, not on the wires.
Pry the rear mount off the radio.
Installation
With the radio removed, remove the removal tool. To do this, press the side tabs on the radio inward.
Attach the rear mount to the radio.
Plug the plugs into the back of the radio.
Slide the radio receiver into the front panel until it locks into place in its shaft.
Connect the negative cable to the battery.
Turn on the radio and enter the security code.
Set the clock.
