I'm thinking Om Star and/or blue tooth, Remember what I said in another one of these posts Some of this stuff cant easily be added,
Ron you definetly have my interest now.
I am figuring this out as I am going with it. I am pretty sure the golden connector is the XM radio one (which I don't have/want, you need an extra receiver and antenna for that.) The blue one is the GPS antenna. The two black ones, in the harness, take the two plugs the basic radio has (the basic radio only has two plugs + antenna, so my wild guess is it will make the AM/FM part work) The AM/FM antenna goes in with an adapter too. GPS only needs an antenna, so I expect that to work too. Of course DVD and CD-audio etc, doesn't need anything else (probably)
So I guess, AM/FM, CD audio, DVD, and GPS should work. The other connectors (wild guess) are for the rear seat audio etc. (if that would ever work).
I am sending the radio to a "OEM radio guy", that will unlock it for me.
The dealership wanted $247 for unlocking the radio (even if they couldn't get it to work or permanently lock it, I still had to pay it.) They also told me they had to re-program all the RPO-codes... (my reaction was: "Whaaaattt????". (oh and it was between $3 - $5 per code, depending on the code.
Pretty sure it's a rip off, so I am sending it in, the OEM guy guarantees it will work in my vehicle after they are done with reprogramming it.
After it 'all' works, I might be up for an experiment and see if I can get the harness that runs through the console and hooks up the rear audio. I read in some description (the conversion harness will retain the optional installed rear dvd and rear audio). If that harness is not too terribly expensive, I might just get one and give it a try.
Anyway, I'll keep this updated, if anyone is interested.
