This project is to outline the steps you can take to hook up steering wheel control buttons from a stock Nissan NV200 van — onto an aftermarket stereo unit with standard remote control capabilities. At first I was going to buy an adapter but became confused at the many different models and high prices of available kits at Crutchfield and other stores. After looking closely at wiring diagrams I realized the there are only 3 wires needed to hook up the NV200 steering wheel buttons to the aftermarket stereo unit…in my case a Sony XAV-68BT. You do not need any fancy connectors, just a standard 3.5mm headphone jack plug…cost about 3 dollars at the dollar store or just cut one off an old headphone unit like I did.

Now to wire it up, all you need to do is wire up the 3 wires on the main NV200 radio plug connector to the three wires on the headphone 3.5mm jack. Ground wire is the big section on the headphone jack, and the other 2 sections get attached to the other 2 data wires…data-1, and data-2. Please see the diagram picture to select which terminal to use. The black wire is Ground…STRG-GND, the green and red wires are the STRG-A and STRG-B . I don’t know which is which (A or B) so I just guessed and it worked so either I guessed right or it doesn’t matter. In my opinion, it probably doesn’t matter because when you program your new stereo to the NV200 steering wheel buttons…one by one, the radio simply assigns the relevant buttons you push to whatever data comes down the wires. If it wouldn’t have worked, I was simply going to reverse the 2 wires and then try it. In my opinion, you can’t do any harm by hooking the 2 data wires reversed, because they would be high impedance data wires and not capable of doing any harm.
I chose to splice the Sony Stereo wires directly to the main NV200 radio white connector wires so it leaves the other end open for the 3 remote control wires. After the system tested good, I simply bent the wires over as shown in the picture and securely taped them so they don’t fall out. Of course if you want to, you can splice the wires directly onto the NV200 radio connector wires but in my case it was getting a bit crowded back there with the spliced speaker wires so I left it alone and just plugged the steering wheel wires into the front of the connector as shown. A 22 or 24 gauge solid wire makes a good secure electrical fit into the female end of the connector.

If anyone has any questions, just leave them in the comments section and I will try to respond.
