    Posted: 26 Jun 2011 at 8:25pm
as title states can it be done.... the orginal cd unit was jammed up. Its not my car i was taking a look as a favour. The owner went out an purchased a new headunit with an ipod connection and an autoleads adapter for that model according to halfrauds ... So what i thought was going to be an easy plug and play has turned into a nightmare that i dont need on a sunday night.
So after looking at the plugs and what halfrauds had sold her, and then going up to halfrauds myself to argue that the plug is not the right one and getting no where i got out the test probe and had a probe about
I have found a permanent feed, illumination and ignition feed. . . . can the orginal earth be used and if so which one is it or is it better to run my own earth

The next problem is the speaker wires can anyone tell me the colours so i can cut the plug and connect up to the new unit.

I have tried the display with the aircon with the cd unit disconnected and everything else is working fine so i was thinking of just hooking up to the required feeds which i have already located and hopefully the speaker wires are just a case of cutting orginal plug and solder up to new plug.

Any help is much appreciatedErmm

Oh dearUnhappy i don't think you are going to like this. The Units supplied in the P12 are integrated in to the electronics and especially the sat nav system (you have nto told us your model version) I have checked our 'how to' section and specialist ICE section that you will ot have access to . I can not find any post that has been successful upgrading the unit. There are however other ways of integrating MP3 players.
I can tell you that the aerials act as the earth and form the circuit for the power

ok well its not the sat nav model its the poverty spec modelLOL (1.8s P12)
it has just the basic cd unit slot at bottom of dash.. i have disconnected that and the plugs are hanging out the dash
i cant see how it wouldnt work hooking up an aftermarket unit as the aircon and display all work, all the buttons on controls work
obviously just none of the audio functions work and no audio display on the screen
i have sourced the power feeds i need
i just wondered if anyone knew the colour of speaker wires that way i can trial a fit by hooking up new system to the the required feeds and speakers then if all going well i would then mod the slot in dash to accept the unit

OK, the best thing to do is go to our 'How to@ section at the top you will find a link to a free download of the electronic service manual, the info will be found there

Hi bud - I've got an ISO connector lead in front of me that I used for a while to connect a Parrot handsfree kit (which can also be used to fit aftermarket headunits).  If it helps, the 2 grey leads are right front pos/neg, the purple/black are right rear pos/neg, white leads are left front pos/neg and the green ones left rear pos/neg.  I'm pretty sure the colours did match my P12 speaker wiring.  Hope that helps mate.  Cheers  Simon

it has been done, IIRC, there was a guy from Scandinavia who successfully fitted an aftermarket headunit to a P12.

as for off the shelf harness adapters, i'd be amazed if you ever find one.

download the P12 FSM here:

http://www.npoc.co.uk/forum/nissan-primera-factory-service-manuals_topic29493.html

i haven't read it myself, but it should contain wiring diagrams etc.

right cheers for info ive got the manual and on research i think i can figure it out using the following
front left + = L (guessing is blue ?? ) front left - = LG (blue/green) pins 6 and 5
front right + = Br (brown) front right - = Br/W (brown/white) pins 8 and 7
rear left + = L/G (blue / green) rear left - = B/Y (black/yellow) pins 10 and 9
rear right + = L (blue) rear left - = P (pink) pins 12 and 11

im sure ive got what im looking for but if anyone spots a flaw let me know before i go short out her nice new stereo LOL
cheers
