adnguyen23 @DUDU-Meng UPDATE: I ran the Bluetooth firmware update and it's now stable. Thank you!
2015 (9th gen) Honda Accord EX-L V6 Issues
adnguyen23 The subwoofer output is connected correctly, but you must go to “Settings” - “Sound” - “More Settings” - “Turn Subwoofer Output On “ and turn the volume to maximum (10)
This car does not have a radio antenna.
There is no RCA connector in the 12P connector for the left/right radio audio output? Look for it, find it and connect it to the left/right audio input of the DUDU device A connector!
dudu-lai I am not seeing an option for "Turn Subwoofer On" - could you please tell me where it is?
Little update on item 4 (km instead of mi) -- I have made the change here, but my top screen still shows km which is why I think it's programmed in the TFT box.
EQ setup - no subwoofer option?
dudu-lai I tried all these settings from these screenshots, but nothing affected the subwoofer.
adnguyen23 This is the subwoofer output setting. If there is no sound, check that the subwoofer is working and that the wiring harness is correct.

dudu-lai I plugged the OEM head unit back in and confirmed the subwoofer works. I placed my hand on it and could feel the vibrations. When I put the Dudu7 back in the subwoofer stopped working (no vibrations).
Here is the 12-pin connector you mentioned
When I was plugging the Dudu7 back in I noticed one of the cables has multiple wires coming from the car, but only 3 going to the Dudu7
Finally I did some testing for the unused cables...
- When I unplugged the big grey one it removed power from the OEM head unit.
- When I had the radio on I unplugged the small grey one and lost signal. Plugging it back in restored FM radio.
- The green cable might be the OEM microphone, but I didn't test a phone call because it doesn't matter.
Hopefully these wiring diagrams help. I am still trying to locate the subwoofer wire.

adnguyen23 Verify that pins PA3 and PA9, PA4 and PA10 in the figure are subwoofer audio
dudu-lai the 12 pin connector goes to the Canbus decoder
I plugged the OEM head unit and can confirm this 8 pin connector goes to the subwoofer. The pins look correct on the Dudu harness so I am unsure what's causing a signal issue.
adnguyen23 You're right, I got confused. 12P is radio audio. Does the radio have sound now?
dudu-lai the radio does not work. Please see a previous post where I mentioned one of the unused cables good to the radio antenna.
adnguyen23
Is there 5V at PIN4 and where is the PIN8 cable connected?
Will I get sound when I connect the subwoofer RCA connector to the left front audio output on Zone A?
adnguyen23 Did you do that? Play the stock radio in this app
dudu-lai I plugged the subwoofer RCA into the left/right front/rear and nothing changed. Getting the subwoofer working is my #1 priority at this point.
The radio app does not do anything. This unused connector is what goes to the radio antenna.
Also whenever I go into the AUX application it shows my right turn camera. Is that normal? I plugged my phone into the car's aux port and I cannot hear anything.
adnguyen23 Please record a video demonstrating how the radio is operated.
The AUX app shows the right camera, which is normal
dudu-lai https://photos.app.goo.gl/5vaGfVUsfegCuvbA7 here are videos of both radio apps.
Also I have not checked Pin 4 of the 8-pin connector yet because I do not have a multimeter.
