OK. So the unit is partially installed.
Firstly, anyone with the same vehicle as mine who is later looking at this post:
In order to remove the head unit, you need to first remove all of the plastic trim from the far left (beginning with the large piece under the wheel, then the top and bottom of the wheel shroud, then you have access to the two screws holding in the trim covering the head unit. There are another two screws on the right side (after you remove the vent trim). Afterwards, there are screws holding the head unit in, and voila! I ordered, but did not use the Metra trim for my vehicle (Metra 99-7614 Nissan NV/Quest 2011-UP Single and Double DIN); the brackets from my factory head unit worked just fine. And since the screen completely covers the opening, I did not see a need for any additional trim.
What is working:
- Factory antenna (I used this part: Metra Electronics 40-NI12)
- Regular head unit functionality (I used this wiring harness: Metra 70-7552)
What is currently not working:
- The factory backup camera
- The factory USB port (located under the a/c controls)
- Steering Wheel Controls (SWC)
- CAN connection (I do not know what to purchase)
I had ordered this for the backup camera: Axxess AX-NIS32SWC-6V. But, after I got it, upon further investigation, it seems that I also need this: Metra Axxess ASWC-1 Universal Steering Wheel Control Interface. So I ordered the ASWC-1, as well as a female mini to regular male USB adapter. The factory cable coming from the USB port under the a/c controls has a mini usb connector. So I purchased the adapter to be able to retain that plug (and avoid having to stick a USB in the glove box, or somewhere else).
Am I missing anything else that I need? Will the ASWC-1 that I purchased allow me to use factory backup camera as well as SWC? Worse case scenario, the Joying has two wires labeled Key 1 and Key 2 which I can splice into my factory wiring, and manually program. I would prefer to splice as little as possible, though.
Is there anyway I can retain the factory GPS?
Attached is a picture of the harnesses from my vehicle.
Starting from the far left: The blue plug is for the GPS; the black one is the mini USB; the 24-pin plug with nothing plugged into it, is I believe the SWC; the plug with a harness plugged in is the main harness; the gray plug second from the left is the radio antenna (with the adapter I purchased plugged in); the pink plug is unknown. The pink plug is in taped up with the antenna, and is routed together with it as far as I can see into the inside of the vehicle. Interestingly, there is another plug (seen in the faded background, bottom right), that is tied up with the main harness, but was not plugged in to the factory head unit. Maybe to save costs the wiring is the same from one trim level to another trim level, and that harness would be for one without NAV, or something? Any ideas?
So to sum up: I still need SWC, backup camera, and maybe factory GPS. Also, can someone please advise me what to purchase to allow connection to my canbus?
Anyone with some knowledge greater than mine, care to help?
The unit is great, though. Amazing screen, pretty quick. All-in-all, so far so good!
