I just installed a pioneer Navigation in my 06. its a AVIC-D3 I can't seem to get any sound out ot if. Please Help
Thanks

 

Are you using the OEM amps/speakers? Which interface adapter?

I just put a D3 in my '07 a few weeks ago, kept the OEM amps with a Scosche GM09SR adapter, everything worked fine except for some alternator whine that I took care of with a power filter and some ground loop isolators.

 

yes i am using an OEM Amp/Speakers. It is a bose system and i am using a GMOS-04 Harness from Axxess.

 

I had this same problem when I installed a Pioneer nav system in my Porsche. Everything is perfect, but no sound.

The problem lies with "powering-up" the EXISTING amp that came in the car. You will not get sound UNLESS the Corvette amp is turned on (and currently, it is NOT receiving a signal to "turn-on".

If you examine the wiring harness ON THE PIONEER UNIT, there is a wire that is used SPECIFICALLY to TURN-ON your car's built-in amplifier. You will then have to figure out which wire ON THE CORVETTE harness turns the CORVETTE AMP on.

You'll have to find a wiring diagram for the Corvette to find out which wire to tap into. Once the car's factory amp is turned-on, you WILL get sound.

 

Whick wire on the D3 turns the amp on

 

humm. i think i just found it in the manual - I'm going to take a look. Thanks

 

the blue&white wire is attached to the blue&white harness - All is correct there.

 

Still Can't get any sound. PLEASE HELP. I would llike to put my car together so i can go drive it.

 

I'm at work right now, so I don't have any of my notes or the service manuals handy. I'll look at them when I get home in the morning to see if anything jumps out at me.

 

Cool - Thanks - Pittsburg Steelers and you live in SC???

 

I'm a yankee transplant. Love the 'burgh, hate the weather!

 

Same here, I'm from Vermont, wife from NJ. Transplants ourselves - we can drive sports car down here ALL year round.

 

I had the exact same problem and called Metra. You'll need to cut the blue/white wire coming out of the GMAS-04 and going into the GM harness. You then add a 5 prong 30 amp relay (I used a 4 prong 60 amp because that's what I found at Radio Shack), the back of the relay will have the numbers 30, 85, 86,87, 87a (if 5 prongs) next to the prongs on the back. On the relay you hook ground up to prong 86, 12v fused constant to 87, the blue/white from the GMOS-04 box (the one you cut) to 85, and the blue/white other side to 30...if there's a 87a you don't use it.
Mine works perfectly now

Hope this helps!!!

This might help:

 

There's your answer, it sounds like the gizmo can't put out enough juice to run the OEM amps, so a relay is needed.

Dogue, that diagram is perfect, but I think you got the numbers a little mixed up in your first post.

FYI, you can get a relay at Radio Shack for $6.79

 

Thanks for the help and i will try it today. But before i went home i started the vet and it was skiping real bad. I cut the vss wire that i hook up to the green/white wire at the ecm and the skip was gone but the engine light is on. I followed the directions from this post. http://forums.corvetteforum.com/show....php?t=1490531 must not be the wright wire anyone have a idea?

 

Your link is incomplete, you only copied the abbreviated visible portion of the address, not the entire thing, so I don't know what green/white wire you connected to, but if your original radio was Bose you can find the VSS wire behind the radio, check out the second picture in post #2 of this thread

Adding the relay is pretty simple also, pins 30/87 are the coil (either can be ground or power), and pins 85/86 are the closed contacts when power is applied to the coil.

 

Put 12volts on the blue&white going to the GMOS-04, as a relay would also do. And only 5 volts will come out of it. so i put 12 volts on the output side and the amp did power up and music was playing but when you shut the driver side door the music turns off, and then music comes on very LOW. Open the door and volume comes back up. As for the VSS wire I'll figure that out after the radio works.

 

I didn't use a GMOS-04, but it sounds to me like that's the problem. The thing is, you don't need it to turn on the Bose amps, the D3 will do that.

The GMOS-04 monitors the cars data line and uses that info to send 12V out through the red wire in order to turn on the D3 when the cars computer says "radio should be on now". That's how it retains RAP. It sounds like you have that part working just fine.

Once the D3 is powered up, IT sends 12V out through the blue/white wire (coming out of the D3) which is supposed to be used to power up your external amps (in this case the OEM Bose amp).

What you need to do is forget about the blue/white wire coming out of the GMOS-04 and connect the blue/white wire coming out of the D3 to the 24 pin harness. Is the blue/white wire coming out of the D3 connected to anything right now? If it is, I'd disconnect it before doing anything else.

The blue/white wire coming out of the GMOS-04 should be going to the 24 pin harness at pin B3 and match up with a white wire on the GM side. Right?

What I would do is cut that blue/white wire, tape off the end going back to the GMOS-04, and connect the end going to the 24 pin harness to the blue/white wire coming out of the D3. That would give you a 12V supply to the Bose amps whenever the D3 is powered up.

For your other problems:

The VSS lead on the D3 should be connected at the 12 pin plug as per the other link. It works fine like that in my '07, and shouldn't make the engine miss IMO even if it was hooked up wrong.

For the door controlling the volume levels

I have to get ready for work now, hopefully I'll have time to surf a bit tonight and be able to check back later.

 

I was able to get the radio to work by bypassing the GMOS-04 with the amp wire and disconnecting the mute form the GMOS. But i still had to supply the GMOS with the amp out of the D3 or else if i shut the door the volume would go down. Everything appears to work just fine, except for my speedometer, its jittery. Any ideas on that. Thanks for ALL the help...
