I got a a new radio. Pioneer avh x5500 Bhs. I have 2009 cobalt lt. I have the gmos lan 04. Followed the wiring instructions. Connected them right. Hook it up to my radio. It comes on but I hear nothing. It's not like I could wire the speakers wrong since it's RCA, right?

 

The guys at metra said its because I can only use the gmos lan 03? I thought base models could use gmos lan 04??

 

if metra said you can't use it...

but ya the 03 is for the non amplified applications

 

Yea I did. For $100. It hurt buying it. I could of sworn on multiple threads. Base models without pioneer could use it.

 

damn that sucks bro maybe try selling it

 

Yea I have an ad on here. But these kind of things usually take awhile to sell.

 

I need help figuring out what wiring harness I need for a 2.2 with only 4 speakers.

The gmos lan 04 didn't work.

I called they said I need gmos lan 03

So I order that one. Which I'm waiting for.

Found a gmos lan 03 gm lan 11 on eBay for a good price. Is that the same thing?

Also I went on axxesss website. They said I need their gmos lan 034.

Which one do I need!

To many wiring harness. Just want to have my radio in and working.

 

the harness u found on ebay is the regular gmos lan 03... look at the pic idk why the seller labeled it as the lan 11 thats stupid

 

Yea it threw me off. I might bid for it. But in the description it says it's new but they tested it to see if it works and I saw recent bad reviews say there stuff doesn't work.

I emailed the axxess people about it. They didn't really answer my question about the difference between gmos lan 03. Gmos lan 034. Gmos lan 03 gm lan 11. But they told me I could use the LC-GMRC-LAN-03. Which takes out onstar. $50 cheaper.

 

well the 034 is newer maybe it supports access steering wheel controls where the lan 03 does not? or they made it for a certain newer model car and it has overlap with the balt?

 

It probably might do that. I get the wiring harness today. See if everything goes right.

 

The wiring harness works good. The radio is fuzzy bc my antenna is messed up when I move it around the Channels clear up. Now the gmos lan 3. Is damn messy. So many wires everywhere. The connectors I used are garbage. So I'm gonna some different ones. Thinking about taking this one back and getting the LC-GMRC-LAN-03. If it's less wires. The gmos lan 04 is much easier set up then gmos lan 03.

 

just tape up and zip tie the wires. We have a pretty big dash opening and can be bigger if u cut the plastic so room shouldn't be an issue

 

Yea I'll clean it up later when I get different connectors. These suck. Not giving it a full connection. But most of the time it does.

Yea I cut out the plastic and took out the metal bar.

Just need to figure out the radio problem. Not finding any channels. Everything is fuzzy. Expect one. At one time. I could hear channels. But very fuzzy. I can't tell it's my antenna. Since it's off track. But that shouldn't stop it from getting signal

 

Yea it's antenna. When I move it around. I can hear it get less fuzzy.

 

i would check the factory connection inside the truck to ensure it is secure. If so then not much else you can do other than replace the antenna

 

Yea I probably might have too.

Do you have a aftermarket head unit? This isn't a bid deal but when I turn my auto lights off. The sound on plays through one radio then right back to all of them. It's odd.

 

I have a 06 SS with the same headunit and nothing happens when I trun lights off. That is pretty odd..

 

The gmos lan 03. Is very odd wiring harness. I have 2 ignition wires. I just left one alone. maybe it's for an amp? I don't know. I'm gonna fix some wires with different connectors. I might just get the other wiring harness. That doesn't retain onstar. Since that one seems less of a mess.

 

I also have 2 illumination wires.

 

I called metra. They said I have to hook up both ignition wires together. So that would be 3 in total being hooked up? Also does everyone have a relay box that makes your chimes work on y'all's wiring harness? On the gmos lan 04 kit I bought before I got the gmos lan 3 didn't have it.

Maybe the ignition wires has something to do with it? With the whole lights thing

 

maybe but that sounds like a ground issue. is the ground wire secure? do you have the right one hooked up? If you have a bad ground then the radio will get its ground from the antenna. and if the antenna connection in the truck isnt secure which is somewhat likely then its going to be an even worse ground then it already was

 

I don't have a ground wire. I have a micro bypass.

 

what the hell is that
