I have few questions still regarding my car stereo installation.
1. Back up camera- I connected red positive wire and black ground wire (that came with the camera they supplied) to my reverse light wires on Nissan altima 2006 ( I spliced the black ground wire and red with a black stripe wire just after the wiring harness meet towards the reverse light. I also connected yellow RCA wire back of my head unit and on the other side to camera. I do see camera when I put the reverse gear, and camera goes off if I switch to Drive or to parking, but I had to choose camera mode on my head unit to be able to see this. On the back of my DVD unit I have brown wire (which is meant for reverse), I left this unconnected. Do I need to connect this also to the red positive wire of the reverse light by running an extra wire from back of head unit to reverse light again, so that reverse camera comes up automatically when I switch to reverse gear ( without me having to select camera mode)?. I tried connecting the brown reverse wire to my Red Ignition /switched 12 V wire, but this seems to keep the head unit in power always and it remains in camera mode always and does not allow me to change into DVD disc or navigation or any other available modes like radio, tv, usb, aux etc.
2. I have connected “Ouku DVD head unit” to my Nissan altima 2006 using a Metra wiring harness ( it had two adapters) but there was no steering wheel control adapter. I cut the wires going into steering wheel wiring harness that has 3 wires (Blue, green with white stripe, and red with white stripe). Grounded the blue wire to one of the black wire of the head unit, fortunately there is a second black grounding wire from the same outlet of the wiring harness of the head unit and I used this to ground a pink (parking) wire from the head unit so that I was able to see the video while driving. Grounding of blue wire restored trip function on the altima, So I can change between Trip A, Trip B or dte or mpg etc. I connected the remaining two wires which were originally going into steering wheel harness into steering wheel key1 (green with white stripe wire) and steering wheel key 2 (red with white stripe wire) and programmed steering wheel control options using Wheel under settings in my head unit. It seems that one wire is for steering wheel control power cable +5 V and another wire (black) is ground cable and this leaves just one more data cable. Though the OEM stereo and steering wheel controls has more controls all are fed just from one wire and resistors may be doing the trick to get multiple controls to work.
But while programming the steering wheel controls, I was able to save just one function either vol + or Vol- or skip (next or previous track or station) or Mod ( which is allowing me to switch between radio, TV, DVD, navigation, camera, aux, usb, i pod modes) , all work but I have to choose just one of them. I read somewhere in this forum that Nissan uses just one single wire and multiple resistors to make several steering wheel controls work. (see this under this link "http://www.crutchfield.com/S-1H7KplQPrXK/learn/2005-06-nissan-altima.html" Nissan uses a single wire for every button on your steering wheel. The PAC adapter requires multiple resistors to distinguish between the different signals from the steering wheel controls, Is there any way of getting back , vol and skip ( next or pre ) functions to work , without having to use steering wheel adapters. Because I was able to program each one of them, but it is saving just one (last programmed option).
