I finally got all the dealer wiring skematics for the 2007 base head units , and the upgraded XM/onstar radio....same skematic for 6-disc and non-disc , pioneer amp , radio controls and the digital reciever for XM . Before anyone screams why theres no pics , I will post them tomorrow morning in this thread Anyways , looking at my 05 skematics ....every single wire is exactly the same color , same purpose . There arent any extra wires in the 07 . All the wiring was exactly the same , BUT .....arranged differently in the new style connectors . So you would still need to remove the wires and terminals in the old connectors and put them in the right place in the new connectors . To remove the wire and terminal from the stock connector you just depress the retainer clip inside and it just pulls out . Then simply pushes into the new connector and locks .

There may be one hitch though .....and its probably gonna take someone just trying it to find out . While the 05 , 06 and 07 all have the exact same low speed lan connection to the BCM . I dont have any clue if the 2007 radio is gonna communicate with the 2005 or 2006 BCM . If it wont your screwed .......but after seeing all the wiring , I would bet the 07 BCM signal is the same .

Someone will probably beat me too it , but if not I will be purchasing a brand new XM/Onstar ready 6-disc HU to try this out within a few weeks .

 

nice then we will have an I-Pod hookup!

 

NO DOUBT THAT WOULD BE AWESOME SICK OF THE STATIC!!!!

 

be very careful with the 2007 radios i don't know about the cobalt radio for the 2007 but i know other radios like the one for the tahoe aveo hhr are totally different connectors than for the cobalt. I REPEAT NOT ALL 2007 GM MODELS FIT THE COBALT. The 2007 cobalt radio i don't know if it fits previous models but if it doens't their is a solution to make it work you gotta get an OEM REVERSE WIRE HARNESS and will work guranteed.

 

He said that the connectors are different, that's the whole point of the thread. The connectors are different but the wires themselves are the same. What he's doing is basically the same thing as getting a reverse wire harness. Taking the wires out of the old plug one by one and putting them into the new one, arranged properly.

 

some people just don't read very carefully

 

taking the wires out of the old one well depends if your moving from old radio to a new radio or new to an old radio so it depends

 

Ummmm.......no it doesn't. If the wires are the same and do the same jobs, it doesn't matter whether you go from new to old or whatever. The wires and connectors don't know if they're newer or older. You're just taking the wires out of one connector and putting them in a different one.

 

.....like playing connect the dots ...YO!

 

No you missed what he is saying. There are around 3-4 radios for 2007 in GM vehicles. They use the same plastic CONNECTORS, but the PINS are in different places. So a 2007 HHR radio will not work in a 2007 Cobalt, etc.. without modifying the stock wire harness.
This is a little different than what the original poster said, as all the 2005 GM vehicles shared the same connector pin out across all vehicles.
To put it another way that might make more sense. For 2005 most GM cars could use the same Metra wiring harness because the connectors and pins were all the same on all cars. Now, metra will have to make wiring harnesses for each car, because each car is wired differently.
I'm kinda making a generalized statment as I'm sure not EVERY SINGLE vehicle will have a differne t pin out, but you get the point.

 

Weeze i agree with you 100% however i believe what you are saying is not the origional posters intended meaning. in fact i'm not quite sure what was meant by the ramblings of djblass since the origional poster was talking abotu going from an 05 or 06 radio to the 07 radio with the 6 disc CD changer. that was the only kinds of radio mentioned. noone ever mentioned putting an 06 radio in an 07 or trying to put an HHR radio in a cobalt so i don't know where djblass was getting that from. i'm not saying his information is incorrect however i am saying that noone here was trying to take an HHR radio and put it in a cobalt.

 

I'm just saying original poster just needs to be sure to get a 07 cobalt radio and not an 07 radio from a an ion, hhr, avalanche, etc... Most people buy OEM radios from ebay, since even discount GM parts stores online still want $400+ for the stock BASE level radio. The radios all look VERY similar, it would be easy to buy the wrong one on ebay if the description is not explicit.
That $400 radio can usually be had for $100 on ebay, sometimes even less. IMO, crappy Delco radios are not worth full price. Their quality/durability/logevity versus cost is not very good.

 

i think he sounds like he knows his ****!

 

The Cobalt black tie radio will only work in a Cobalt . The face plate is specific to match the slight curve on the cobalt center stack . I have a HHR and Avalance black tie head units and they will not fit the opening correctly int he Cobalt dash , as the face plates on those are completely flat .


Got held up on the diagrams . They will not be up until tomorrow . My scanner will not work so I have to scan them all at work tomorrow and throw em on a disc .

Found out one more thing ...the antenna wiring is definately different . 07 uses 1 coaxial cable . The 05 , 06 uses 2 switched 14volt wires . Is there an a adapter maybe to switch the 05-06 antenna wiring to a coaxial cable ?

 

the 07's use a chrysler antenna adapter (yeah I know, WTF) instead of the GM antenna adapter. I dont know of anyone who makes an adapter to go from the chrysler female (radio) to GM male (car) or vis versa if I got that backwards. I suppose you could by a gm and chrysler adapter and try to splice them together.

 

Yeah I see what he was saying now in his second post. I was just making the point that if the connectors are different but have wires that do the same thing, the wires can simply be removed from the connector and put in a different one. That would have the same effect as a reverse wire harness. But from what you're saying the 2007 radios for the HHR etc have different wires then the Cobalt.

 

this is definitely something i am interested in, keep me posted!!!!
so youre basically saying, if we switched the wires on the harness, and got someone to create a coaxal converter, it would work....idk how likely this is, we still havent found a company who has an aux input adapter that will work for our car...
the radio controls the computer, so on an 06 would u be reading the computer from the dash? or from the radio?
also, does anybody know what functions you can access on the new radio computer? on the panflit for the cobalt, it says there are 14 computer functions....what are they?

 

Sounds like a lot of trouble to me when you could just go aftermarket!! Stock radios suck no matter where they come from. Good luck to you though in your endeavor and thumbs up on trying something different.

sure do look better though in the dash

 

so if i wanted to get an 07 radio for my 7speaker and blah, id have to get cobalt one?

if i have a cobalt that is of course...

 

Any updates on this topic?

 

I'm looking for some updates too...
