Topic: 07 Non-Bose Avy - purchased stock Nav unit

[Scott41677]

Hi All,

I posted this in the other forums so I apologize for duplicating this topic...but I need some assistance.

I have an 07 non-Bose Avy. I purchased the stock Nav unit from someone who also has an 07 non-Bose Avy. In doing my reading I see that I need 3 things:

1) GPS antenna
2) VSS harness
3) Dealer to unlock the unit once installed

Here's the catch...the guy I purchased the unit from lists the part number as:

GM PART # 25925495
DELPHI PART # 28128781

When I look up the GM part number it comes back as a Buick Enclave Nav unit...not an 07 Avy.  However I verified that the seller had an 07 Avy and this unit was definitely from that vehicle. So since the unit is being delivered tomorrow, I really won't know if the seller typed the number wrong or is lying.

So at this point...can someone tell me where/how to get the VSS harness as no local GM dealer seems to know what I am talking about.  Once the unit comes tomorrow I'll be able to see the actual part number.  Hopefully the GPS antenna part number won't matter

Ok, thanks for the reminder. I'll look at our resources here in a few minutes.

Here's the GM part number for the antenna  GM#15201798

I've got a part number for a harness but I'm not sure what all is involved in that yet. Still digging.

Thanks OBB. I am going to call Century 2000 tomorrow when I get home to see if they have a VSS harness that I can use.  I have called 2 different GM dealers and neither of them have the GPS Antenna in stock...go figure.

I'm trying to find out if that's the same one that mine uses. Did you get those pix I asked about?

[Scott41677]

Not yet.  I am in Los Angeles at the moment but will get pics tomorrow when I get home and the unit is delivered.

Do you have the rpo code that came in your glove box for the radio by chance?

[oHIobellboy]

Not yet.  I am in Los Angeles at the moment but will get pics tomorrow when I get home and the unit is delivered.

oops. forgot about that.

[oHIobellboy]

here's two pix depending on which rpo code you have to add the VSS pin to the back of the plug. I think I have pins to do this if there isn't one in the plug.





either way it's the Dark Green/White wire that sends the signal to the head unit.
I'm looking now for the cluster pinout. I got interrupted by a phone.


looking at the cluster pinout the same color wire is for the DIC switch signal so we don't want that one.

Wow OBB...I can't thank you enough for the diagram!  It looks like with this I can run just a simple wire from that pin to the back of the NAV unit. I'll look for the plug layout of the NAV unit tomorrow when I get home.  Looks like this might be a project for tomorrow rather than Saturday...lol
