13-17 Leaf S Radio Install Guide

I thought I’d post all of the parts that I used to install an aftermarket radio in my ‘13 Leaf. This works on the 13- 17 Leaf S. For the 16-17 Leaf S disregard the phone button retention harness as they have no BCM. Feel free to ask any questions.

- Dash Kit: American International NDK780

- Wiring Harness: 70-7552 - 20-pin Subaru/Nissan Harness with SWC from
This has all the required wires, plus it has the correct steering wheel pins unlike the Metra Version and they even ground pin 15 for the steering wheel controls.

- Antenna Adapter: Metra 40-NI12

- Backup Camera Adapter: Axxess AX-NIS32SWC-6V
This worked in adapting the Leaf’s back up camera. Just follow the instructions on this link: ... 6V_web.pdf

- Phone Button Retention Harness (13-15) : AXXESS AX-NIS32BT or PAC BT-SWC-NI1
13-15 models only. 16-17 have no BCM. In order to retain the two phone buttons you’ll need to use this adapter to bridge the lost connections when unplugging the BCM. This makes it much easier then trying to jump the wires yourself. You’ll have to gain access to the BCM in the rear luggage compartment. Use this forum post as a reference for disassembly:

- Steering Wheel Control Adapter: Axxess ASWC-1
Please use this link from AXXESS to connect the steering wheel controls adapter. It didn’t work for me initially but I swapped the Gray/Blue wire to Pin 6 and Gray/Red to Pin 16 and it works perfectly:

I just install an aftermarket Android head unit, called SilverStrong 707x5 for Nissan, in a 2014 Leaf S.

Whats worked out of the box:
  • The unit was equiped with one connector for the fm antenna, and the 20pin connector for power and speakers etc. These connectors seems to be standard, when you order a head unit for Nissan.
  • The unit powers up.
  • Speakers are working
  • Fm radio is working
  • The steering wheels buttons for volume up/down and source up/down are working. The unit has an app to map buttons to functions.
  • The unit was equipped with GPS-antenna.
  • It worked to install apps for internet radio, webbrowsing, navigation and maps with traffic information, apps for finding charging stations and to start and stop charging etc.
What is not working out of the box:
  • The car has a second white connector for backup camera and mic etc. I am missing cable between this connector and the head unit's mini jack for mic and yellow connector for the backup camera.
  • The backup camera is not working.
  • The microhpone is not working
  • The 2 steering wheels buttons for phone are not working..
  • Facia frame is needed. There is a gap on the right and the left hand side of the unit.
I am wondering if the Axxess AX-NIS32SWC-6V Backup Camera Retention will do the job and is needed, or if anything else will to the job.

What works partly:
  • The unit has no sim card reader and i used a 4G USB dongle. When the car boots up, it takes a couple of minutes to get internet connections. A workaround might be to run hot spot from the phone.
I liked the original radio, with all of its buttons, that should make it easy to control. Unfortunate the screen was to small and it did not support bluetooth audio, and it did not support maps with traffic information in the rush hour. Usually i listen to internet radio while driving, and here in Norway there are not many FM stations left, and there are many stations of Digital Audio Broadcasting that will not work well with the original head unit. On the old unit i can't run Leaf Spy Pro or OVMS.

The build microphone can be used for OEM stereos with a little adapter. The Leaf uses a Mic Amp that amplifies the microphone signal and adds about 2 V DC to the signal as documented in the manuals found at OEM Stereos require an un-amplified signal without DC component. The little adapter uses a capacitor to filter out the DC component and then a resistance divider to lower the mic signal. I have used that circuit in a 2016 Leaf with both Sony and Pioneer Radios and it works well. You need to make sure to provide 5V to the original Mic Amplifier, which you can either take from a USB output of the OEM Stereo or any USB adapter.


The 2015 and earlier models provide 5V from the original BT module, which can be reused as mentioned at The 2016 and later models do not provide 5V other than from the original Stereo.

Do i have to take the mic signal from the trunc, or is there any short cut so i don't have to move the back seat?
To get the 2 phone buttons on the steering wheel working, i connected this to the plug in the trunk: Axxess AX-NIS32BT
Instead of the AX-NIS32BT, i see chumpp is just strapped the plug with some loop-wires.

I recently picked up a CarPlay compatible unit from Amazon and used this list for all the necessary items. In my previous car I used CarPlay exclusively for everything, and prefer it over any other infotainment system. I did skip the Phone button adapters as I just don’t use them currently, seemed like an unnecessary cost and extra work. Planning to use the mic that comes with head unit, but may explore integrating it into the factory mic, we’ll see. Thanks for the list, will post before and after once all arrives and it’s installed.

So I spent the better part of Sunday morning completing this install. Pictures to follow later. Here is a complete list of all the items I bought to make this work:

BOSS CarPlay Head Unit - I only wanted CarPlay so I can access Apple Music, podcasts, basically anything via my phone. Northern Nevada doesn't have many great FM stations... ... UTF8&psc=1

Metra Axxess ASWC-1 Universal Steering Wheel Controller - I've had success using this before in a previous vehicle. The main harness that comes with this won't be used, as you will use the harness that comes with the 6V kit for back up camera. More on why this doesn't currently work in the Leaf down below.... ... UTF8&psc=1

Axxess AX-NIS32SWC-6V - This is to retain the factory backup camera. The wiring harness that comes with this will replace the harness that comes with the ASWC-1. ... UTF8&psc=1

Ai NDK780 Dash Kit - This is a near match for the finish of the dash area around the radio. The mounts however didn't line up with my was a radio issue and not this kit. Still made it work via some two sided foam tape. ... UTF8&psc=1

Metra 70-7552 Wiring Harness - Main harness for speakers to radio. ... UTF8&psc=1

Harmony Audio HA-40NI12 Antenna Adapter - Figured since I was inside I might as well hook up antenna in case I needed it ... UTF8&psc=1

Metra AX-NISUSB-2 USB Retention Harness - Used this to maintain the factory USB port on console. This way I didn't have to run any additional USB cable down the back to use Apple CarPlay. ... UTF8&psc=1

AXXESS AX-NIS32BT Steering Wheel Controller Adapter - Had to buy this after the fact as I didn't know I needed it originally. ... lsrc=aw.ds

What works:
-the stereo
-retaining factory USB
-rear back up camera

What doesn't work:
-steering wheel controls

After trying to program the ASWC-1 for a few hours, I gave up, and put everything together, tested out function (minus steering wheel controls). Pretty impressed with this head unit as it packs a punch, and was a great value at $126 total. For the steering wheel controls, going to continue work on that today. I believe this may be a radio issue more than vehicle issue, as the auto program feature appears to work, and goes to a state that indicates it detects the vehicle. However, I can't change the radio type, so I'm not sure. I wasn't going to retain the phone buttons as the head unit/CarPlay has the necessary functions for that. But for $10 and lug and play, I figured why not. Plus it was available for local pickup.

So the ASWC-1 with the AX-NIS32SWC-6V is a finicky luck yet. Multiple calls to tech support ranging from they don't support the Leaf all the way to questioning my lack of understanding english....(I was born in Ohio)...Still trying but the work week is fast approaching, this may spill to next week or later...

Thanks for your updates- how much did you pay for the Boss head unit? Amazon has it at $220+ now
