Removal and installation the radio (BMW 3 Series E36)

Factory-installed radios come with different mounting options.

If the receiver has a sliding mount, it allows for quick removal and installation of the radio. However, this can only be done with a special tool that is included with the radio or is available in the store.

Removal

Disconnect the ground wire from the battery.

Caution: When the battery is disconnected, the information in the electronic memory devices, such as the engine fault memory or the radio security code memory, is erased. Disconnect the battery only when the ignition is off, so as not to damage the fuel injection system control unit. When disconnecting the battery, follow the instructions in the sections "Radio" and "Removing and installing the battery".

Note: On vehicles with a six-cylinder engine, the battery is located in the luggage compartment on the right side next to the spare wheel.
