Plastic disassembly levers, suitable screwdrivers or bits depending on the connections used, or extraction tools depending on the design of the radio are usually needed. Prepare protection for the surrounding surfaces, a flashlight and, if necessary, a multimeter. If the car requires a car radio configuration, the corresponding diagnostic equipment is required.

3) Step-by-step assembly procedure

1. Stop the car safely, turn off the car radio and ignition and follow the service instructions for preparing the electrical system.
2. Wait for the prescribed sleep of the electronics and disconnect the battery in the manner specified by the car manufacturer.
3. Protect the surrounding surfaces and gently loosen any covers preventing access to the radio mounting.
4. Release the fasteners or locks of the radio with the appropriate tool. Do not force the front panel.
5. Carefully pull out the radio, document the wiring and unlock the connectors. Do not pull the cables by the wires.
6. Compare both parts side by side and check the condition of sockets, contacts and attachment points.
7. Connect the connectors to the replacement car radio and secure their fuses. If the connector does not fit, do not use force or adjust it.
8. Store the wiring so it doesn’t get pinched behind the radio body, and secure the radio properly.
9. Connect the battery according to the manufacturer’s instructions. If necessary for the given design, have the radio set up or paired by a suitable diagnostic.
10. Verify the basic functions and then complete the deployment of the remaining covers. Check that everything is firmly in place and that nothing is strained.
