Removal and Installation of Radio
REMOVAL
1. Remove the volume control knob.
2. Insert a screwdriver into the slot next to the volume control shaft and turn it 90°. Remove the screwdriver to the left and, together with it, pull the control panel out and move it to the right.
* If the screwdriver does not go straight into the slot, insert it, turn it 90°, and thus shift the latch to the right while opening the slot at the same time. Turn the screwdriver further and insert it into the slot.

3. Disconnect the electrical connector. To do so, pull the clip to the side.
4. Turn the two radio mounting screws (3) counterclockwise with an internal hex key so that the radio can be easily removed.

5. Disconnect the multi-pin electrical connector (1) using a screwdriver. Disconnect the ground cable (2). Disconnect the antenna lead (3).

INSTALLATION
1. Connect the multi-pin electrical connector and antenna lead to the rear of the radio. Secure the ground cable with the screw.
2. Insert the radio into the instrument panel opening.
3. Tighten the internal hex screws.
4. Connect the multi-pin electrical connector at the radio control panel. Close the clip and secure it.
5. Insert the control panel into the vehicle instrument panel opening until it locks into place.
6. Install the volume control knob.
