How to Remove a Car Stereo from an Astra
- 1). Open the Astra's hood. Turn the nut on the negative battery cable with a wrench, and then detach the cable from the post.
- 2). Move to the driver-side seat. Insert the first key into the left radio holes. Insert the second key into the right radio holes. Push both keys in firmly to disengage the spring clips inside.
- 3). Pull the Astra's radio forward. View the back to find the two harnesses. One is for the antenna; the other is for the stereo. Unplug each harness to separate the radio.
