Hope you get it working. Might not be for you but bluetooth is 'to me' the best part of the whole system.

It was working on the Base Radio. I have a Bluetooth Adapter that plugs into the AUX port, so it's not that big of a deal, but just wanted to keep everything OEM working.

Since the original was only 16-pins and the new one is a 32-pin connector. Was there something that needed to be spliced differently? This post mentions a different module needs to be purchased, but doesn't say which one.

Are you still on this? I did a similar upgrade on my Versa15.
What I had to do was to short 3 pins in the bluetooth unit that was in the back trunk in my case. Yours sound like a similar case. Read back a few pages in this thread.

I think that may help? Could you explain a little further as to what you did?

I upgraded from the Base Audio version to the OEM Display Audio Radio (28185-3WC0A). I didn't change the Bluetooth unit.

What I did was this.. https://www.nissanversaforums.com/255722-post27.html

The thing is that your upgrade unit has already bluetooth built in. So you don't need the bluetooth unit that is in the trunk. So, when you press a button in the steering wheel control, the signal is sent to the back unit not your Audio unit. Shorting those cables, returns the signals back to the Audio unit. You really need to read back all the previous posts in this thread. The pin diagram on your unit may or may not be the same.
These shorting would make the buttons work, but the mic will still be non-functional. The mic signal is also with BT unit, for that to work you have to draw couple wires from the back unit, and feed them to the mic input of the audio units.

That one only works if you got the 28185-9MB0A which contains the Bluetooth Phone and Media.

I have the 28185-3WC0A which is only Bluetooth Phone and it still has to go back to the Bluetooth Unit.

In that case, it should be an even easier fix for your unit. You need to check the service manuals for your car (the AV section), and the service manual for the model where this 28185-3WC0A unit came from. The right signals should be there, but Nissan may have moved them around a bit. So, you will have to move those cables.

The 28185-3WC0A came from the 2014 Nissan Versa Note. It was the upgraded model from the Base Audio version. I found the AV manual and it looks like it uses the same Bluetooth Control Unit. Any tips? I took this into a shop to do it and they weren't able to figure it out.

Just got done swapping a radio from a 2015 Sentra with display audio into my 2015 Versa SV sedan. Everything works. In the end, I kinda wish I'd just gone to best but and bought an aftermarket nav head unit.

I finally had some time today to look into your situation here. The difference between the Base Audio and Display Audio (28185-3WC0A) is the 16pin vs the 32 pin connector. The other connectors are common. You have to splice the 16 pin connector wires in your dash. Purchase a 32 pin harness from ebay, like this link. Splice that too. NEW AXXESS AX-NIS-ADDCAM1 NISSAN BACK-UP CAMERA ADD-ON HARNESS | eBay

You gotta basically compare the pin diagram in page 19 and 78 of the manual. Pin 1 to 20 are the same. Then look for common pin description from the next one.

From what it looks like.

Base Audio Pin - Display Audio Pin
31,32 - 24,25
30 - 26
22, 24 - 46, 48
27,28 - 31,32

I believe this should get your unit fully working. Don't take my word for it. Verify the pin diagram yourself. I believe you can add a back camera too, if you are interested.

Hi Colonel Clink, i see you are the Master of knowledge in here!

I want to ask, Cyberuffy started the forum by saying after he installed the updated OEM Radio, his mic connection and streering will voice/phone command was not working. Now i have a Sentra and i just installed the unit in sublimesed pic #3 and got the same exact issue. Now with what you stated with the Bluetooth Module im already searching to order the sophisticated module. once i install that, will i need to do anything else to get the bt functionality working?

Thanks Colonel Clink
