Frequently Asked Questions - CDX-C5750 SONY

How do I install the Sony CDX-C5750?

Ensure the car battery is disconnected. Use the provided mounting sleeve and trim ring. Connect the ISO wiring harness: yellow for constant power, red for ignition, black for ground, and speaker wires accordingly. Slide the unit into the sleeve until it clicks.

Why doesn't the CD eject?

Press the eject button firmly. If stuck, turn off the unit and use a thin object (e.g., paperclip) to gently press the manual eject hole. Do not force the disc.

How can I improve FM reception?

Check the antenna connection at the back. Ensure the antenna is fully extended and free from corrosion. If using an aftermarket antenna, verify it matches the ISO connector.

Can I play MP3 CDs on this model?

No, the Sony CDX-C5750 is designed for standard audio CDs (CD-DA) and CD-R/RW discs recorded in audio format. It does not support MP3 or WMA files.

What is the detachable faceplate used for?

The detachable faceplate serves as a theft deterrent. Remove it when leaving the vehicle and store it in a safe place. To detach, press the release button and pull the panel outward.

How do I reset the unit?

Press the reset button located on the front panel (usually recessed) using a pointed object like a pen tip. This clears settings and may resolve minor glitches.

Why is there no sound from the speakers?

Check speaker wiring connections. Ensure the unit is not muted (press the mute button). Verify that the fader/balance settings are centered. Also, test speakers with another source.

Can I connect a CD changer?

Yes, the CDX-C5750 has a proprietary CD changer control port (usually 13-pin). Compatible Sony CD changers (e.g., CDX-757MX) can be connected for extended disc playback.

What should I do if the display is dim?

Adjust the dimmer setting (if available) via the menu. Also, check the illumination wire (orange) connection; it may be tied to the car's dimmer circuit. Ensure proper voltage.

How do I clean the CD lens?

Use a dry cotton swab or a lens cleaning disc specially designed for car CD players. Do not apply liquids. Gently wipe the lens in a circular motion.

Notes on handling CDs

A dirty or defective disc may cause sound dropouts while playing. To enjoy optimum sound, handle the disc by its edge. To keep the disc clean, do not touch the surface.

Do not stick paper or tape on the labeled surface.

Do not expose the discs to direct sunlight or heat sources such as hot air-ducts, or leave them in a car parked in direct sunlight where there can be a considerable rise in temperature inside the car.

Before playing, clean the discs with an optional cleaning cloth. Wipe each disc from the center out.

Do not use solvents such as benzine, thinner, commercially available cleaners, or antistatic spray intended for analog discs.

Note on moisture condensation

On a rainy day or in a very damp area, moisture may condense on the lenses inside the CD player. Should this occur, the unit will not operate properly. In this case, remove the disc and wait for about an hour until the moisture evaporates.

When you play 8 cm (3 in.) CDs

Use the optional Sony compact disc single adapter (CSA-8) to protect the CD player from damage.

Maintenance

Fuse replacement

When replacing the fuse, be sure to use one matching the amperage rating started on the original fuse. If the fuse blows, check the power connection and replace the fuse. If the fuse blows again after replacement, there may be an internal malfunction. In such a case, consult your nearest Sony dealer.

Warning
