Installation recommendations
Generally/typically for replacing a car radio the procedure below applies. The exact steps may vary depending on the specific design of the dashboard and the equipment of the car.
1) Before assembly (checks of the used part, what to compare with the old part)
- Compare the product codes on the label/unit body (see above) with the old car radio.
- Check the condition of the connectors (bent pins, cracks in the plastic, traces of oxidation) and mechanical damage to the front panel.
- Verify that the type and number of connections (main connector, antenna, any additional connectors depending on equipment) match.
2) Necessary tools and materials (in general, without specific extra parts)
- Set of plastic pry bars for panel removal
- Suitable screwdrivers / bits (according to design)
- Flashlight
- Electrical contact cleaner (optional) and dry cloth
3) Step-by-step assembly procedure
- Turn off the ignition and wait for the car to “sleep” (common practice in modern cars) to be safe.
- Disconnect the battery (recommended to protect the electronics and prevent a short circuit).
- Remove the surrounding bezel/dashboard trim around the radio using plastic pry bars.
- Loosen the fixing screws or loosen the unit lock (depending on the design).
- Pull out the car radio so that you can reach the connectors without pulling on the wiring.
- Disconnect the connectors (main harness, antenna connector and any others) – always by the body of the connector, not by the wires.
- If necessary, clean the contacts and check the connectors for dirt or moisture.
- Plug the connectors into the replacement car stereo and make sure they click into place.
- Sit the unit back into the hole and secure it with the fastener.
- Refit the bezel/trim.
- Connect the battery.
- Turn on the ignition and test the functions (power on, sound, controls, CD drive).
-
4) Post-assembly checks and test drive/function verification
- Verify that the sound does not drop out and that the radio responds stably to controls.
- Try the CD drive (insert/eject, read).
- Check radio reception (antenna) and basic settings if necessary.
5) The most common assembly mistakes + how to avoid them
- Exchange without code comparison → always check numbers 9666994580 / 1611729080 / 1613842980 / 6574SN.
- Pulling on the wiring → disconnect/connect the connectors only by the body of the connector.
- Installation without disconnecting the battery → there is a risk of short circuit or damage to the electronics, especially when handling the dashboard.
- Cables pinched when inserting → before final tightening, check for free harness routing.
Reasons why the part is damaged
- CD drive wear (loading problems, jams, won’t read media).
- Voltage fluctuations in the on-board network (weak battery, bad charging, peaks at start-up).
- Moisture and oxidation of connectors (worse contact, sound drops, unstable operation).
- Mechanical damage to the front panel or connectors during unprofessional disassembly.
- Overheating and aging of electronic components over time.
