2007 Oem Nav Upgrade

[hm3tocapt]

I'm going to buy a GM OEM nav system from e-bay for my NBS 2007 GMC Sierra 1500. I have the Bose, Onstar and XM. I do NOT have the rear seat entertainment system. The unit I am looking at buying has the head unit, GPS antenna and nav disk but no user's manual or install instructions.

 

Does anyone have any pointers for me or places where I can get an owner's manual or install instructions?

 

thanks in advance.

I bought the radio tonight and I think I got a good deal. I got what appears to be a new head unit for $589 plus shipping from ebay. The thing still has the plastic on it. Now I just need to buy the antenna and disk.

Good luck the disks are expensive. The antenna not so much.

 

Here is some info from a tahoe forum, its the same set up you have

 

For anybody that owns a new 2007 Tahoe/Suburban or Avalanche with Bose (most front bucket seat equipped Tahoe's have the Bose speaker/amp system) and wishes to install the factory OEM Denso Navigation system here is a complete set of instructions and list of parts to accomplish the job:

 

First off you'll need the head unit Part #15882767 if your vehicle does NOT have factory DVD or 15882766 (new updated version of this unit is Part #15940102) if you DO have factory DVD, Ebay can be a good place to find one of these head units.

 

You'll also need the GPS antenna part #15201798 these sell for about $50 at the dealership.

Rear back-up camera part #15173619.

And finally you'll need the GM 2007 Map DVD part #15934919 for the most current release (v2.0) or 15807780 for the earlier version (v1.10) the changes are very minimal and mostly in the eastern regions.

 

The install is straight forward:

Remove the wood trim panel surrounding the radio and HVAC controls, there are 9 clips holding it to the dash and they are stubborn, be careful not to ding the edge of the stereo when prying this off.

Next, remove the fasteners holding the head unit (10mm heads).

 

Now remove the A-pillar covers by prying the access plug out on driver side and remove the fastener(s), remove the grab handle on the passenger's side and unplug the tweeter leads.

Pry the front top dash trim panel up (5 clips total) and unplug the photocell light sensor, you'll see just to the right of the center there is a square area with a clip built in that holds the GPS antenna, snap it into place and fish the wire down towards the head unit, you may have to remove the glove box which is easy and you can figure it out in a glance.

Now reinstall the head unit and the trim pieces.

 

The unit will show a blue screen and the words THEFTLOCK, don't be alarmed this is good.

Now you'll have to take it to the dealer or have access to a Tech-2 device and TIS programs to accomplish the programming/learning procedure.

With Tech-2 connected to the vehicle go to the Service Programming mode and select "get vehicle information” and follow the prompts to download the module info into Tech-2.

Now disconnect Tech-2 and connect it to the Techline TIS computer and enter SPS menu select "radio” and then it will ask you a few questions regarding the radio, amp rear camera, etc, the only tricky one is make sure to select "w/o Y91 option the 2 times it asks and also select "region 1 NTSC” when you get to that screen; when done in the menu download the programming and then connect Tech-2 back up and install the software when done turn ignition off , unplug Tech-2 and wait at least 30 seconds to turn the key back on and your done.
