Removal and installation the radio (BMW 3 Series E30)

Factory-installed radios come with different mounting options.

If the receiver has a quick-release mount, it allows for quick removal and installation of the radio. However, this can only be done with a special tool that is supplied with the radio or is available for sale. The presence of a quick-release device is usually determined by the presence of 2 or 4 holes on the front panel.

Removal

Disconnect the ground wire from the battery.
