Hey guys - I am having some problems doing the wiring with my Z2 and I am hoping someone can help.

The wiring harness for my car has a blue/white amp turn on wire coming from it. The Z3 manual (I upgraded my Z2 => Z3) says on page 15 that RCA connector 1 should have a matching blue/white wire attached that I would connect it to.

My problem is that my RCA Connector 1 has no blue/white wire... It only has RCA plugs (L/R Front speaker, L/R Rear speakers, L/R 'subwoofer or non-fading output', and L/R AUdio in, video in).

Am I missing something? I can't for the life of me find the blue/white wire anywhere on the Z2s harnesses.

Also - my black power supply connector has 8 speaker wires coming out of it. I assume I do not need to use these if I am using the RCA connectors from RCA connector 1 to hook into my harness. Only short coming is that the aftermarket harness I have isn't really made for my car, and it only has RCA cables for L/R Front/Rear. No RCA plugs for the sub. My car however does have a sub and have wires available. Can I cut the sub RCA cables and directly connect the +/- wires into my car?

Any help would be GREATLY appreciated.

Thanks in advance!

No thoughts guys? I am going crazy here trying to get this wired in. Does anyone else know if there really was a blue/white wire on their RCA connector 1?

Yes, there should be a blue/white wire for amp turn on in the RCA1 connector. These pictures may help you identify the correct location for the blue/white wire.

Also, you can NOT cut the sub RCA connector to power your sub. You will need to determine if the sub has an amp.

Damn. Mine definitely does not have those wires (the mute or the amp on). I have attached the photo of the Z2 RCA connector 1 harness I received with mine.

Mine was second hand so it is possible those two wires were yanked. There are two empty pi/wire slots on the harness, on the leftmost side (beside the right audio input wires). However i can see on the HU that there are pins for those two slots. I assume that one is the unnecessary mute wire and one is the amp on. Any idea which on the amp on is? That way I can put a wire in there myself rather than having to order a whole new harness. I tried searching for a pin-out diagram of the Z2 connectors to no avail.

The sub does have an amp, however it is the same amp that the speakers go through. the Metra harness I am using has rca plugs for the 4 speakers, allowing me to plug them into the amp, but does not have ones for the sub.

Thx.

The second missing wire is the yellow/black mute wire. It was most likely moved to connector 2 for the 2 wire bypass...

Other possible wires that could be moved and used in place of hte blue/white:

Blue wire in the power connector: only used if you have a power antenna or antenna booster.

Violet/white wire (reverse) if you are not planning on installing a backup camera.

I can't help with your sub wiring without knowing how the speakers/amp are configured.

You could also use the yellow/black 'guide on' wire in RCA connector 2.

I have attached the page form the service manual that shows the pinouts on the back of the unit. Please note these pin outs are looking at the back of the AVIC Z and not the connector.

Garret, you are the man.

I will use the 'guide on' lead in place of the blue/white wire.

What exactly is the guide on lead meant for? Mute an external device when the nav voice comes on?

I am installing it in a 2004 Land Rover Discovery, which I hear from everyone at the local A/V shops & land rover forums is notoriously bad to try and integrate an aftermarket system with. Apparently their amp is very proprietary and you lose the sub functionality. I will play around a bit and see what happens. Worst case scenario is I just redo the wiring from scratch and ignore the OEM wiring.

Cheers!

Yellow/black (GUIDE ON)

When combining this navigation unit with the

multi-channel processor system, connect this

lead to yellow/black lead on the multi-channel

processor controller unit. In this way, when the

mute signal is output from this navigation

system, the audio volume is automatically

muted or attenuated.

Hey guys, I have a similar problem and tried your advice posted above. Here is my situation:

I have a 2006 Chrysler 300 and I bought the Metra CHTO-01 adapter harness to install my AVIC-Z2. I have made all of the wiring connections except for 1:

The CHTO-01 says to connect its blue/white wire to the radio's amplifier turn-on wire. On the Z2 unit I cannot find the amplifier turn-on wire, and there is no sound in my car speakers. The weird thing is that I have also installed an amp/sub in the trunk previously and connected it into the wiring for the rear speaker for a signal. The sub works now, but the speakers inside the car don't. I tried connecting the blue/white wire from the CHTO-01 to the blue wire in Connector 1 that is labelled "System Remote Control", but it is the same situation.

When I play a dvd I only get sound in the sub. When I use the radio (AM or FM) I don't even get the sound in the sub.

I tried changing the settings you guys talk about in this post but no luck.

ANy suggestions?

Thanks,

Samz
