Steering Wheel Control issue after radio swap

4406 Views 5 Replies 6 Participants Last post by  amc49
I swapped out my factory radio of my 2015 Versa Note SV with a new Kenwood touch screen and added the ASWC-1 for retention of steering wheel controls. I wire all of it up as shown, and it shows it finds it as a Kenwood but controls didn't work. Tried setting them up manually and only could get volume buttons to work. When I tried to program seek up nothing happened nor with Seek down. Has anyone else gone through this before? Also is there a way to retain the factory USB port with aftermarket radio. I am fine with the Bluetooth being a aftermarket mic and through headunit.

Not sure if this helps. I had a Sony Carplay head unit installed in a 2017 Nissan Versa S Plus at Best Buy. They tried installing the same steering wheel interface and could only get volume to work. They ended up installing a Maestro - Universal Analog Steering Wheel Interface and got almost everything to work. Volume, Source, Radio/Track Seek. Phone answer works as long as Carplay is active. Not perfect, but better than before.

So did the "call cancel" button ever work since the "Maestro" was installed?
I have installed a Boss head unit into a 2017 Nissan Versa S
  • I used a [Maestro] {ACC-BT-NI1} jumper plug for the BT module bypass in the trunk.
  • I used a ControlPRO 2 {SWI-CP2} by [PAC] and their web instructional guide.
- connected SWC/SWI "Analog 1,2 & Ground" pins 6,16&15 as directed along with traditional power and speaker wires for both devices on the 20 pin car stereo harness connector.
- set dip switches as directed for specific car year and model and stereo brand.

The Source, Seek +/-, the Volume +/- and the Call Start buttons work as expected, (a little different than factory but acceptable).
- I see the SWI light flash green (from its resting red power indicator light) letting me know that the button I press is triggering it, it in turn, triggers my function on the radio, and the function I expect.


Though all others will, the Call Cancel button will NOT trigger the SWI to flash green, so I don't expect, and do not get, any response on the radio.
-The call cancel button worked before the aftermarket unit so I suspect the issue to be in the voltage translation between the output of the steering wheel function button and the expected interface in the SWI.
- I DO see an open lead condition when "call cancel" is not depressed and a constant resistance when depressed (I was in a hurry just confirming condition change and constant so didn't record.)

Does anyone know of an electrical diagram I can get my hands on for 2017 Nissan Versa S, so I can test the individual resistors ohms impedance and verify proper voltage output from the steering wheel button presses?

As far as the SWI
  • I have been unable to connect a PC {windows} via USB (nothing recognized by anything)
  • I attempted the manual (1 pushy button, 1 flashy light) programming process and it makes no difference, so I reset to default as per instructions.

Another issue, after driving for a day or so, the "seek +" randomly triggering from somewhere and a tuner up signal and the head unit does its job and just goes on surfing. [Has anyone had this one]?

Does anyone know where to find a chart or diagram for the actual meaning of what on and off for the 8 (car) and 4 (head unit) dip switches actually do on the "ControlPRO 2 {SWI-CP2} by [PAC]"?
- What their values are and expected input/outputs per setting?

If I am able to figure out how to interface with PC, or find a better arrangement for dip switches or programming, can this resolve my issue?

Is the Versa just a Cursa and I'm just stuck with no call cancel button?

Thank you anyone for your feedback and/or productive input/knowledge resource direction.
