Re: Steering wheel controls for radio
I know this is a bit of an old thread and there is other stuff on the forum about this but I only just did this yesterday and thought I would share my experience, it is exactly how Ian describes. 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.
