2015 (9th gen) Honda Accord EX-L V6 Issues

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.

dudu-lai

adnguyen23 Did you do that? Play the stock radio in this app

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

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

dudu-lai I do not get 5V from any of these pins while the car is on and music is playing. I confirmed my car battery shows 12.46V when the car is off and 14.29V when on so I know the multimeter works.

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.

You can purchase an external antenna to use with the DUDU radio

dudu-lai Thanks, where would this plug in?

I will try to pick up a multimeter today for the subwoofer.

PIN4 input 5V level

adnguyen23

dudu-lai Could you please clarify? I checked Pin 4 and do not get 5V from it.

Also I plugged the external antenna into connector 8 and the radio apps are the same as before.

adnguyen23

dudu-lai I called 5 different car audio shops near me and most will not take a look at my car. One suggested that I reach back out to request the correct decoder for my car since that shop would not be able to source the correct part.

dudu-lai

adnguyen23 What radio app are you using?

adnguyen23

dudu-lai I tried both. Honestly I'm fine if the radio doesn't work. Not having a functioning subwoofer has been more annoying than I thought it would be.

dudu-lai

adnguyen23 PD4 inputs 5V voltage to test whether the subwoofer works

adnguyen23

dudu-lai Is there something you would like me to test? I put the OEM head unit back in and the subwoofer works.

Also do you have a TFT box that shows miles instead of kilometers?

dudu-lai

adnguyen23 PD4 inputs 5V，Have you ever tested it like this?

adnguyen23

dudu-lai Could you please confirm if this is how you would like me to test this? https://www.youtube.com/watch?v=xIMHGkxw72o

Also please let me know about the TFT box with miles instead of kilometers.

adnguyen23

@dudu-lai I gave up trying to troubleshoot the subwoofer and bought an aftermarket one which works fine.

Please let me know about the TFT box. FM radio is fine now.

I don't have any screws for these trim pieces. Please let me know what size is best

These are the only screws I received.
