After market stereo/navigation

[the evil twin]

G'day Evil,

From what i can tell, yes it's a VDO Dayton, when i removed the factory double din i think from memory i removed 3 plugs but only utilised 2 of those plugs with the Eonon unit. I used aeropro adaptors for installing
so the original nissan plugs are still there.
It appears there is no power to the nav unit under the seat,i will check with a test light tomorrow morning, dash lights are all working.
Im going to remove the eonon tomorrow and have another look around and see if i have missed something.

Thank you all for taking an interest.

Cool... I asked about dash lights as a lot of times people get the Head Unit earth and illumination wires confused and blow the dash light fuse.

I am not 100% on where Nissan fitters grab the power for the Sat Nav as my issues were all done under warranty but as it is ACC power then a bit of sleuthing should sort it out. I would be very suprised if they didn't use the head unit power.

Seeing as how the Head unit is working tho it means the fuse must be OK so maybe that "third" plug is the problem

As I mentioned prev to Yendor the Head Unit should be a straight swap (mine was but mine is an 07 ST) but sometimes there are issues getting the logic from the steering wheel controls set up

Hiya Yendor,

the older VDO's are dumb as dog doo doo .

Lol,doesn't stop Nissan from charging bullshit prices for them.

It's not so much Nissan... It is VDO.

I think the Daytons retailed for $2800 and were a top end Sat Nav for their time. Whille that is still a rip, you have to remember they are a full Sat Nav not just a GPS and have accelerometers/turn sensors/speed averaging etc.

Telstra don't miss out either charging $200 for map updates and you can't use (hack) anyone else

Oh, by the by, I can confirm that my Dayton runs off a feed from the Radio fuse as I went out and pulled the sucker out of curiousity. Where it actually splices in to the wiring I am not sure.

[Yendor]

I would start by checking the fuses.

Fuse 10 and 28 in the fuse box inside the vehicle and fuse 56 under the bonnet. These fuses do run other electrical items so I don't really think these will be blown.

Have a look around the radio incase you have left any other connectors disconnected or accidentally dislodged a connector.

There is also a control unit for the Nav system mounted below the radio, so have a look at the connectors below the radio as well as above.

The wiring diagram I have doesn't show exactly where the the Nav systems picks up the power from, just that it runs through fuses 10 and 28.

It does show that the ignition feed wire changes colour between the fuse and the Nav system but it doesn't show a connector.

What colour wires are in the original plug for the radio that you have left disconnected?

[Moatmonster]

Righto,pulled it out,all fuses good. Photos of what i have got
This is the plug not used.

[Moatmonster]

These are the 2 plugs used with the aeropro connections

[Moatmonster]

And this is the back of the Factory Nav unit

[Yendor]

The light green, purple and the black wire will be for the steering wheel stereo control. They shouldn't stop the Nav system from working.

What happens if you plug the original radio back in?

[Yendor]

At the display unit the Blue wire with the Orange trace should have power when the accessories and ignition are on.

The Red wire with a Green trace should have constant battery.

Only use a voltmeter to test.

[Moatmonster]

Success, what a dumb arse. I tracked the wiring back from the factory nav back towards the stereo and found a male and female plugs with the same colour wiring as the aeropros.
Piggy backed them in and what do you know, power to the sat nav and camera.

Thank you to Yendor and Evil for all your help, i would have been still looking if it not for your input.
