The Comand NTG4 can be found in W204 chassis cars, C Class (C200, C220). We commonly see these units for jammed CD drives where it won’t eject the disks in it or it could be loading but not playing the disks. Sometimes we see these units where they have lost sound, especially with the Harman/Kardon amplifier based audio systems, believe it or not, we find that the fault is most commonly located in the head unit itself, not the amplifier (Which is located in the rear left of the car in the boot) so best to send both the head unit and the amplifier to us.

The Repair Procedure
Ready to get your stereo repaired? There are two possible steps; read on
- Australia Wide – If you’re not a local to us
The majority of our repairs turn up at our workshop in a box and leave in a box so we are custom to this method. The method is usually as follows
- Contact us by our contact form or by phone to answer any questions you may have with your stereo before sending or just send away! (With our repair form in the box so we know who’s radio it is when it arrives)
- Removing the stereo out of your car. You can get your local auto-mechanic or auto-electrician to remove your stereo, a friend or even take it out yourself! We may have a removal video for your stereo.
- Pack your stereo in a box with plenty of packing material to protect it – It may have an issue but you still want it to turn up safe. Make sure you have filled out our Mail-In form and placed in the box (You can find it on this page). Once filled out, our system will automatically email you your repair form to put in the box. If you can’t print the form, the email provides information on what to put in the box.
- Send it off to us, once arrived we book in and start the diagnosis/repair process. From here we will be in contact along the repair process
- Once repaired, tested and payment finalised we freight your unit straight back to you.
If you’re a local to us you can drop the Stereo off at our workshop if already removed from the car, or we can book a time for you to bring the car to us to have the Stereo removed. Please call us on 1300 211 773 to confirm a booking. Sometimes we can have an exchange unit available for on the spot repairs, otherwise, we would remove the radio from your car and set you on your way with your car minus the stereo for repairs.
