Hey I have a 2004 g35 coupe with the factory nav and after looking I have been able to take out my stereo and get it ready to wiring the metra 70-7551 harness to a pioneer avh-p3200bt. I also have a DPDT and SWI-PS steering wheel control. Could you help me to know how to wire the metra, DPDT and the SWI-PS to the pioneer avh-p3200bt? Thanks so much

 

To keep the nav voice, you attach the specified wires like in the attached diagram to the 12v DPDT relay, in addition to the regular wiring that goes on for the radio install. To make it as easy as possible, pick up a female RCA connector and a male RCA connector with a few inches of wire attached to them (or cut an rca extension cable in half).

For wiring the headunit harness to the Metra 70-7551, refer to the x920bt's manual, but it's mostly just matching colors and functions up, but you have to wire both the antenna amp/power antenna wire AND the remote power/amplifier signal to the remote power signal wire on the x920bt's harness.

The wiring for the PAC SWI-PS you can get good instructions from the PAC website.

 

Thanks so much. I have never done this before so I'm just scared to fry something. But I also want to hardwire my valentine one there. I connected it before and it didn't work where could I connect it?

 

Never worked with a radar detector, my eyes and driving close to the speed limit have always worked for me.

But to power it, I'd look at connecting the power wires to the wires behind the cigarette lighter or the sunroof.

 

shoot thanks. I ran the wire to behind the stereo already I am just looking fo rthe wire to connect it to. Also there are about 5-7 cords that plug into the stock system and I am only going to use 4 of them for the wiring harness, PAC SWI-PS, and stock nav, leaving a couple untouched, is that right?

 

For the radar detector's power wire, you can connect it to the main red power wire for the radio, but I'd want it on a separate for myself, which is why I'd extend it to the cigarette lighter socket's power wire instead.

As for extra cords - Are you talking about all the extra RCA cables coming from the 3200BT, or cords from the car?
The 3200 has video inputs, outputs, subwoofer outputs and aux inputs all that are "extra" cords.

 

Ya the radar detector I would like no connected to the hu at all. The extra wires are the one from the car, the 7 bundles that came out of the stock stereo, would I not use all of them?

 

7... - There's two for the stock navigation, one for the climate controls, three harnesses that plug into the back of the headunit and an antenna wire.
Those are the 7 you're talking about, right?

The two stock nav ones go back to the nav system, climate goes to new climate controls, two of the three from the HU go into the metra harness, one gets cut up and sent to a few places, and the antenna wire gets plugged into the adapter and into the back. That's all 7, and only one doesn't actually get plugged back into a matching harness, if I recall correctly.

 

Ok thanks I swear there wAs one that is untouched. If there are some unused wires is that ok? Thanks so much!

 

Yep, good luck with the rest of the install!
