Removal and installation the radio
Factory installed radios are equipped with a case that allows for quick installation and removal. However, this is only possible with a special tool that is included with the radio when purchased or is available for purchase. The fact that the radio is in a case can usually be determined by the 4 holes on the front panel.
Removal
1. Turn off the ignition.
2. Disconnect the ground (-) cable from the battery.
Attention! When the battery is disconnected, the memory of the radio and electronic control units is erased. VW produces serial radios equipped with an anti-theft code. It prevents unwanted switching on of the device after the circuit is disconnected. The circuit can be disconnected, for example, after disconnecting the battery, removing the radio or burning out the fuse of the radio. If the radio is coded, then before disconnecting the battery, write down the code. If the code is unknown, then the radio can only be put into operation at a service station.
Attention! The individual code number is given in the operating instructions of the radio receiver. The code must not be stored in the car.
3. Insert the two removable devices (A) on the right and left into the holes in the front panel. If there are no holes, remove the control buttons and the shield. Insert the removable devices.
Attention! If you do not have removable devices at hand, insert 4 pins of 1.5 mm and about 30 mm in length into the holes instead, thus releasing the case.
4. Remove the radio without tilting it.
5. Mark the speaker plug connections with tape (right/left) and remove. Remove the antenna. Disconnect the multi-pin plug.
6. Remove the removable devices by squeezing the locking clips with a small screwdriver.
Installation
1. Connect the electrical wires and antenna to the back of the radio.
2. Insert the radio into the instrument panel until it clicks into place.
3. Connect the ground cable () to the battery.
Attention! Connect the battery only when the ignition is off, otherwise the injection system control unit will fail.
4. Set the time on the clock.
5. Enter the anti-theft radio code.
6. Turn on the radio and check the operation. If the radio has a built-in anti-theft code, enter it first.
Instructions for the additionally installed radio receiver
The serially installed multi-pin plug fits all VW radios from 1988 onwards. The plug has the following cable colour coding:
- red - constant plus;
- brown - minus (weight of the car);
- gray/blue – scale backlight;
- brown red – ignition switch on/off control drive (special equipment). Do not connect battery voltage to this drive under any circumstances;
- blue/white – speed signal for automatic volume control (special equipment).
For other radio devices there is a VW adapter.
Attention! If a cable with an adapter is not used, it is necessary to pay attention to good insulation of bare wires. Otherwise, a short circuit and ignition of the cable winding are possible.
Make sure that only proven standard radio interference suppressors are used (general Permit to Operate, ABE). Otherwise, the vehicle's approval for operation will be invalidated. There are specially designed VW radio interference suppressors on sale with installation instructions.
Attention! If the radio will be installed additionally, adjust the radio antenna. To do this, catch a weak medium-wave radio station. Then, using a small screwdriver, adjust to its best reception using the adjusted screw (front right on the radio panel).
