New member,
PLEASE EXCUSE THE LONG WRITE UP
but I do have very exciting news on this front.
I just finished this conversion. Still waiting on an antenna adapter for radio, but that’s not all that important to me.
What you’ll need
1) 19 radio with nav
2) 40 pin female side connnector for the 19 radio. (picked on up at the scrapper out of a 04-07 Murano comfort access module that sits on the passenger side behind the glovebox. Cut it off with a good chunk of wiring to make a conversion harness.)
3) The 20 pin female side connector for the 19 radio. Again, cut it out of a scrapper car with as much wiring as I could. Relatively easy to find as I believe it’s in every Nissan from 07 and up.
4) 20 pin aftermarket radio adapter. Super easy to track down. Again 07 and on is pretty generic.
5) the antenna adapter, they decided that between 17-18, to make the antenna connector slightly more narrow. This doesn’t allow the antenna connector to fit. I have new ones on order that I will modify to make work.
6) 24 pin male side connector. Initially I picked up a piece from digikey, I used loose pins, heatshrinked them and put them in their designated location. Problem when trying to instal the harness, is that the pins tried backing off. So I ordered a Axxess AS-toycam3 Toyota conversion harness for rear view camera retention. Same 24 pin connector as the Nissan. Has a male and female side which I was hoping to utilize the solid wire. Unfortunately, the female pins are different on the aftermarket harness over the OEM 40 pin. But a little bit of splicing and soldering, got the job done.
7) wiring diagrams between both 14-17 and an 18/19. Because I work in the industry, that was not a problem. I am happy to post them if you would like. The only thing that threw me off was that the 14-17 had CAN and M CAN running to the headunit and the 18 has M and V CAN running to it. The M CAN is the important one because of the terminating resistors. After connecting CAN to V CAN illumination and and another function regained normal operation. The 14-17 has a speed sensor wire which is no longer applicable on the newer units. And the 18/19 also has a wire that is not applicable on the older models. But with much tinkering, the system works.
8) USB port for apple car play, currently I am still figuring this out. The phone is plugged in, connects and drops instantly. After 10 attempts... it fails and also does not charge the phone either. The port I have is obviously from an early model. The company called Molex designs our USB ports and there seems to be something extremely fancy about the 18 and up USB ports. What I have found In the wiring diagrams is that the configuration of wiring is setup differently and I’m guessing the port rearranges it in some way to make car play work. The newer ones have a red illumination ring where the early ones don’t. Still in progress. The ports are 260$ CDN which is crazy. I have ordered one off eBay that I managed to scoop up for about 80$ CDN. Awaiting its arrival.
9) 17 and up gauge cluster. The steering controls go from steering wheel, translated by the cluster and sent to the radio. The reason I learned this is because I fitted a 17 steering wheel with heater in mine and the radio steering controls were completely out to lunch. I managed to track down a cluster with higher mileage than mine and drove mine until the mileage was a near match. Then swapped clusters.
9) 17 and up D shaped steering wheel. Why? The steering controls go through the cluster to the radio and as mentioned above, 14-16 do not compute with 17 and up.
So, in conclusion, it does work, lots of modification and tinkering is required, but it is a fully functioning system.
