How do you remove a CD 400 radio from a Vauxhall Astra?

To remove a CD 400 radio from a Vauxhall Astra, first, ensure the vehicle is off and remove the keys from the ignition. Use a pair of radio removal keys, inserting them into the small slots on either side of the radio to disengage the clips. Once released, gently pull the radio out from the dashboard, disconnect the wiring harness and antenna at the back, and the unit will be free for removal. Always consult the vehicle's manual for specific instructions and precautions.
