Not suret. At the back of the head unit, it does have an "IR IN" 3.5mm jack port which I assume is for the SWC patch-leads. I've seen videos of people directly connecting the SWC-KEY+ and SWC-KEY#+ of the ATOTO F7 head unit to their car SWC wires, but they weren't an X-trail and were different colour wires. https://www.youtube.com/watch?v=2Qg4m1hBFv8 On the head unit, you do need to program the SWCs, as in the video above. I guess what I am asking is: which 3 wires in the X-trail are the ones to connect the head unit SWC wires to?

I am happy to start a new thread but thought this was appropriate to continue on with. I've recently installed an ATOTO F7 Android aftermarket head unit into my T31 STL, ad it was pretty easy, except for the steering wheel control. And, I still haven't figured it out. I did notice there are 3 wires in one of the original connectors, they are green, black & red. Are these the SWC-1, ground and SWC-2 wires? Or something else entirely? (https://imgur.com/a/RKKpsDC) If they are the SWC wires, is it a matter of connecting the SWC KEY+ or the KEY#+ and ground from the ATOTO to the wires in the image above, to get the steering controls to work? The Aerpro harness used to connect the rest of the head unit was the CHNIUNI harness (https://aerpro.com/chniuni#). I used the CHNIUNI harness along with the ATOTO F7 ISO-B harness. The ISO-A harness wouldn't keep the memory of the radio stations once the car was turned off. The CHNIUNI harness comes with a Connects 2 device which is supposed to connect the SWC of the X-trail with the head unit. But the head unit did not come with the 3.5mm jack and Molex connector, so I tried using other brand patch leads off the shelf; Kenwood, Alpine, and Clarion. I tried all 3 dip-switch configurations with each patch-lead, but no dice. I do know there are other patch-leads that weren't stocked; Sony, JVC and possibly others that may have worked. I would like to not have to use a patch-lead as I feel like it's a guessing game. There must be a way to know which X-trail wires connect to the SWC KEY+ or the KEY#+ and ground from the ATOTO F7. Any ideas?

Definitely not recommended, just ask any auto electrician or any electrician. nondisclosed_email@example.com (Sxytrail)Fri, 20 Jul 2018 20:52:35 +0000 Re: Steering wheel controls for radiohttps://baustralianxtrail.runboard.com/p2095947,from=rss#post2095947https://baustralianxtrail.runboard.com/p2095947,from=rss#post2095947Hi, For anyone installing an Andriod head unit. Firstly pick up an iso harness of ebay for $20 which will give you pwr, audio and ill. However you will need to do the SWC yourself. Now when wiring up SWC1 and SWC2 from the unit use the information about the factory harness from http://baustralianxtrail.runboard.com/t128598 remember you have to wire in SWC (ground) to the factory harness as well. If you just attach it to any old ground it wont work, took me 2 days balancing a mulitmeter on my legs to work that one out. I didnt cut anything, just scotch locked and duct taped it. Solder is better imo though.

My X-Trail is a T31 Series 5, I installed a double DIN Pioneer MVHZ5050BT, the glory of this particular head unit is you can configure the steering wheel controls directly on the head unit without any fancy (expensive) adapters. Be aware that if you use the Aerpro website and put in the car and head unit details it will tell you that a programable adapter is required which is about 100 bucks, in my setup it was not required. All I needed to do was get a 3.5mm headphone style jack which has three wires, an earth and two signal wires, this jack plugs directly into the rear of my head unit. The other end of the 3 wires are soldered directly into the Aerpro Nissan/Subaru to double ISO harness which is an APP091, the APP091 then just plugged into a double ISO to pioneer harness and it was all good to go. For those that understand how the different stages of the Aerpro harnesses work this is pretty straight forward, there is also a good clip on youtube how they work. I paid about 30 bucks for the two harnesses but realistically if you loved soldering you could connect this HU up and the only expense involved in getting the steering wheel controls working would be the 3.5mm jack. The last bit is really easy, on the head unit you just go to the steering wheel control menu in the settings and in my instance I selected W/O adapter and a Japanese Car, it then went through a process of holding down each button so the head unit could relate the resistance signal from each button on the steering wheel to a specific HU function. The only button that didn't do anything was the information button, I didn't worry about it because I had never pressed it before removing the OEM head unit so I didn't even know what it did in the first place. One thing here that is really important with the steering wheel controls is that because the function on a signal based on the resistance you connections need to be of real good quality, I soldered the three wires to the harness. Hope this is of some use to someone one day.

I've not any experience with aftermarket converters however a trap for some DIYers trying to avoid these would be expecting one wire per control. The steering wheel controls work similar to a switch matrix . That is, the output resistance changes depending on what switch is depressed - this then "controls" the headend depending on the output from the switch combination.
