Steering wheel controls not recognized

Mike

It still isn’t working. It will not stay highlighted and will not learn controls at all.

I cannot seem to be able to upload a short video either. Do you have any recommendations for that so I can show you?

Thanks,

Mike

Mike, thanks for the update.
If possible, please upload the video to YouTube, Google Drive, or WeTransfer and share the link here, so we can take a closer look at the issue.

Also, if the wiring is already consistent with the diagram but the learning function still doesn’t work, we suspect there may be an issue with the factory steering wheel signal wiring. We recommend temporarily reinstalling the OEM head unit to test. If the OEM unit also fails to recognize the steering wheel buttons, this will help confirm the source of the problem.

After reviewing various resources and user feedback for this model, I found that a blown fuse related to the steering wheel module could potentially cause the control buttons to stop working.
You may refer to the following:

Relevant forum post – Other owners of the same model have experienced similar issues, which were resolved after checking the fuse.[Login to see the link]
OEM fuse box diagram – Please refer to this diagram to check if the fuse related to steering wheel controls is in good condition.[Login to see the link]

According to the factory fuse location diagram from this website, the 7.5A fuse at position F72 in the passenger compartment is blown.

I hope this information helps resolve your issue quickly. Wishing you the best!

If the above solutions still do not resolve the issue, I will have to consider the possibility that there may be an issue with the head unit itself. While it is extremely rare for manual wiring to fail in this way, I don’t want to waste your time. If the problem persists, please provide your order number, and I will arrange to send you a complete replacement set immediately.
I truly hope to resolve all of your issues thoroughly and perfectly, and I will not let down the trust you’ve placed in us.

The SWC have power and the fuse is good. The controls also light up as they should.

Hope this helps! Thank you so much for all of the help along the way.

Mike, thank you for sharing the video!
From the video, we can confirm that the CANBUS is working normally—the A/C pop-up appears on startup, and the outside temperature is displayed in the status bar.
However, I did notice that your head unit’s system version is quite old. I recommend upgrading to the latest firmware, as this can improve compatibility and resolve certain functionality issues.

If you don’t have the time to update it yourself, please provide your order number and I will arrange a complete replacement for you right away to ensure the issue is resolved promptly.

Mike

Thank you for the quick reply!

How do I download the firmware to the head unit?

The steering control is the only function that doesn’t work, so hopefully this will take care of it!

Hi! May I ask if updating the firmware resolved the steering wheel control issue you were experiencing?
If the problem still persists, I will arrange a replacement unit for you immediately.

Mike

Leo I also do not have any cable to connect a USB to. Where can I get the cable to do this? Thanks!

Mike

Hi Leo,

I haven’t been able to update the firmware yet. I’m hoping to be able to sometime next week when I can get to the car again.

Leo

Mike
You can update your head unit to the latest firmware via OTA (Over-the-Air) online upgrade to ensure optimal performance and stability.

We found the USB connector and tried. The head unit recognized the USB, but would not start loading. I made sure the files were unzipped and it is a clean USB aside from the download file.

Leo

Mike
Please open File Manager on the head unit → select USB Device, and check the files on your USB drive.
Make sure all extracted files are placed in the root directory of the USB drive (not inside any folder).

Example: Login to see the code is the boot file required for the firmware update. If it is not in the USB root directory, the unit will not detect the firmware and the update will fail.

Mike

The update worked, but the SWC still does the exact same thing it did previously. The lights still backlight the controls, but they just don’t learn on the head unit

Mike
Hi Mike,

We’ve thoroughly checked your unit. Since flashing the firmware and manually connecting the AD wire still didn’t allow the steering wheel controls to learn, it seems the current unit is defective. We recommend replacing it with a new unit to ensure proper functionality.

To arrange the replacement, please contact us at [Login to see the link] or provide your order number in your email, and we’ll guide you through the process.

Thank you for your patience and understanding.

Mike

Finally have an update… The new head unit was changed out and it still didn’t fix the issue. The car was taken to a shop to see if there were wiring issues or anything else going on that was wrong with the car and they could not get it to work either.

At this point, we are going to have to put a different radio in the car. Is this still returnable? I truly appreciate your patience and all the effort along the way to try to get this working.

Hi Mike,

We’re truly sorry for the trouble you’ve experienced, and we really appreciate all the effort you’ve put into testing. Based on the situation so far, since firmware flashing, manual wiring, and even replacing the unit didn’t solve it, our suspicion is that the issue may lie within the factory wiring or steering wheel control module. As mentioned earlier, reinstalling the OEM radio would be the key step to confirm—if the factory unit also fails to recognize the steering wheel buttons, then it’s clearly a vehicle-side issue rather than a head unit incompatibility.

We completely understand your decision to stop the installation at this point. Regarding a return:

If you are still within the Amazon/eBay return window, you can initiate it directly through your order page;
If the return window has passed, please provide your order number and we’ll check if special handling is possible.

Again, we sincerely apologize for the inconvenience and greatly appreciate your patience and understanding throughout this process.
