Wiring VSS and VCIM for OEM NAV/DVD unit
The vss harness is just a wire that goes from the radio to the junction box lower left ip. It is the box by the left foot of the drivers floor board. turn the box around and in the back there are connectors ( I think you are looking for the orange connector).
There are no other modules to buy. You will also need to connect a wire to the VCIM. The VCIM is the onstar module. it is under the radio, below the the a/c. You will need this for voice comands.
You do not need any extra harness its just wires and pins that go into their respective slots. Do you need the connector/wire harness and pins. I can make them and send the pin locations they go to with instructions.

That would be fantastic and I am sure Hossler would appreciate the information as well. The last thing I want to do is fry my entire electrical system. Can you include the VCIM connection information as well?

Can you also confirm if I need a seperate GPS antenna for the NAV/DVD unit or does the Onstar GPS antenna provide this information?
Can you also confirm if the RSE A/V inputs will display on the NAV display similtaneously?
Thank you.

GPS antenna
If your radio is the RSE (DVD symbol on lower right of radio face), it will display rear seat video on radio until you start to drive.

VSS junction box connection
Anyway, it says to look at the back of the junction box located left of the break pedal. Its the only green/wht wire in the bottom big connector. Make sure it goes to connector C4 (brown) pin 5 of the radio.

Are you saying you have these connectors and pins available? I would love it if you could provide them to me and I would be happy to reimburse you. I found the setup on ebay but they wanted $75 bucks. I dont mind paying for something, but I thought that 75 bucks was a bit steep.
Anyway, if you can make them up and send them to me I would be greatly thankful. If you give me your email address I will send you my contact info.
Thanks a million.

This is what i read earlier, but i cant seem to find the thread again. The thread titles was "Can you make heads or tails of this?"

I got the unit installed over the weekend man with out the help of this thread there is no way i would of done it!! THANKS TO ALL. That location of the green/white wire is where you said it was,one of the tuff things was pulling the on-star box out to plug the vcim part of the harness .i also pluged in to the rca jack FOR (BACK UP CAM) for future us so i don't have to pull the dame trim off again.Know i have the theft lock on my question is now that i am ready to take it to the dealer what do i ask or tell them?
Re-read through this thread and you will see more detail for the programming. Its a hugh thread, but this info will be helpful if you have a GM tech that has never done this before. My GM tech at my local dealership says that he is 85% certain it can be done (reprogram for non-lux) which tells me he has never done it, but may have seen the option to do it in the tech II software.
