Issue upgrading 06 Head Unit-Powers up-No audio

I just installed a new JVC head unit (JVC KW-M560BT) in my 06 AC with the non JBL stereo and amplifier under the rear R seat.
I bought the pre rigged wiring harness and amp bypass plug from Crutchfield as well.
Hooked everything up and have power to the head unit, apple play comes up when I connect my phone ,but I have zero audio from the speakers.
Ran through troubleshooting with Crutchfield and the only thing they can come up with is that the new head unit is defective and they are sending another.
I hooked up the original Toyota head unit afterwards and the stereo plays as normal, so not an issue with the amp or a fuse.
Anyone have any other ideas I can try until the new one shows up.
Thanks

 

Did you plug in everything in the HVAC bezel when installing the aftermarket unit?

 

That happened to me.
Turns out I had shorted out the long harness that byasses the amp, when I put the interior back together, a wire got snagged, and it fried my new touch screen's amp.

 

The HVAC Bezel has both plugs attached and is working as normal.
I don't believe its a short in the long harness because the head unit appears to be working fine minus the audio output.
I just draped the amp bypass wires over the passenger seat for now to make sure everything was working before fishing it under the carpet from the amp up through the console. Thanks for the replies.

 

Here's the thing... OEM configuration has the final speaker feed going from the OEM amp to each speaker. You're saying zero of those 4-6 separate wires are getting anything, so you'd need to have multiple wires shorted. Likewise, you'd need to fry every channel on the OEM amp to find yourself in a no sound predicament which is possible but also pretty unlikely.

The amp bypass harness essentially extends the speaker wires at the back of your head unit all the way back to the OEM amp, where it intercepts the OEM speaker leads off that connector. I assume you routed the amp bypass harness back there, unplugging the amp, and plugging the harness Crutchfield sent into that connector?

If "Yes" there's a solid chance something is fried on the new JVC. OR it's possible Crutchfield sent you the wrong thing.

I'd need more details on how you wired things up, and pics of the harness they gave you, out of the vehicle.

 

So was mine.
Everything worked, even the sound for a few seconds. Then the sound didn't work at all and everything else still worked.
I currently have the touch screen with with fried amp in my 06 with a 5 channel amp.

Only other thing is maybe you wired it wrong.

 

The Bypass Harness is Metra 70-8121 Amp Bypass Harness
Attached photo of "ready harness" supplied by crutchfield.

The White and Black Plugs go into the new head unit, The Gray into the existing wiring and the Clear plug into the amp.
That is the only way the plugs fit. They are all specific shaped supplied by Crutchfield

Second photo shows the unit powered on--Just no audio output. not even for a second, no pops

Thanks Again !

 

All the colors are matched correctly? Some have stripes. Other wise I'm out of ideas.

Did the old radio work before?

 

I'll have to line up all the plugs and make sure the colors are correct.
Yes the old radio worked before and still works. I plugged it back in to make sure the amp wasn't fried or a blown fuse somewhere.

 

Check wiring for wrong pin locations. Happened to another customer.

 

Check specifically the white plug with the purple, green, grey and white wires.

Those 8 wires must match exactly on either side of the red connectors. I can’t tell based on the angle.

 

Thank you shifty !!
You were spot on, the amp bypass harness Crutchfield sent had 4 wires out of place.
Working perfect now

 

That's very disappointing coming from from Crutchfield. I hope you express your unhappiness directly to them.

 

Can you post a photo of the corrected plug? I’m having the same trouble currently

 

@Scrotty Welcome to the forum.

 

Tell us more info. His may be different than yours, depending which OEM system you got.

Do you have JBL system or non-JBL?
Post pictures of the amp end of your Metra harness so we can see the wire colors and where in the plug position they go.
Post pictures of the connector at the amp you're plugging the harness into so we can see the wire colors and where in the plug position they go.

I think we can cross-reference the electrical wiring diagram for your truck, which should be similar to mine and potentially OP's unless you have the JBL system.

 

Non-Jbl with the amplifier below the seat. I purchased the amp bypass through Crutchfield. Head unit gets power but no sound from any speakers.

 

Ok that looks like it was the right part, and these two plug together.

Stupid stuff check: You did confirm the volume is not all the way down, and there's no special settings in the radio to turn off speaker output?

It appears Metra has fucked up, and isn't making their part correctly. This is stupid.

Here's how these should hook up, with the wires aligned as shown. This is important in a sec... Note where the red, white, yellow, and black wires are here for the harness on the right. Those are your rear right/left speakers.

​

The first thing I notice is the purple/green appear to be shifted one slot over from the diagrams Crutchfield sent to you in the install kit!! The purple should move one step closer to the notch. The greens should move into the position of the purples. Compare this to what's in your hand above, and notice the two green wires closest to your fingers ... in the diagram from Crutchfield, those slots should be empty.

​

And comparing that to the EWD for our AC trucks, it appears that's your issue... Note the Red (RR+) and White (RR-) in this diagram, in the bottom half on the right.

​

 

@In2bait can you confirm your problem was identical, the purple/greens needed to move over one slot? If so, someone should really get on the horn with Crutchfield and notify them Metra has fucked up on their adapter/harness production.

 

Non-Jbl with the amplifier below the seat. I purchased the amp bypass through Crutchfield.

Seriously a big help. I’ll leave an email for Crutchfield hopefully to prevent this for the next guy!

 

Problem solved?

 

Confirming the amp bypass harness from Cruthfield has the purple and green wires one slot too high.
I had to disconnect the pins and move them down one slot on the plug. The wiring diagram sent by Crutchfield has it correct, but the plug they sent is different
I contacted them and they advised to send the plug back and they would rewire it, but I had already moved the pins.

 

Go to the Crutchfield website and post a review of the item so you can let others know there was a problem with the harness like the other user whose review I posted in post number 10.

 

I ran into the same problem. After many hours of cursing to the wiring gods, I called Crutchfield tech support. They acknowledged the wiring was wrong, but asked to confirm one thing. This is the quote from Crutchfield:

"1. We verified the front speakers are pinned out correctly so, in theory, the front speakers should be functioning (which includes Bluetooth audio).
2. However, what we did notice with the photo you sent, the rear speakers are one pin off.
I am not certain this could be causing your amplifier (head unit internal amplifier or external amplifier, does not matter) to go into protect mode. However, it would be worth disconnecting the rear speaker wires (GREEN and GREEN/BLACK and PURPLE and PURPLE/BLACK) and check to see if the speakers in the front do function."

I had no amp (I pulled out the factory amp that was under the back seat), but was curious if my aftermarket radio unit (Jensen CMR270) had a protect mode, so I cut the wires as they recommended. The front speakers then worked fine.

They're sending me a new harness free of charge.
