Nav Help With 03 Denali

[NateBran]

Hi, I am needing some information on a navigation installation for my 03 Yukon Denali. I took it to the dealer to have my Nav unit installed. They had it ready to go but said when they were programming the vehicle the program would not take. They called TAC for a VCI number to program but they told them non were available for my vehicle.

 

I bought the factory unit on eBay and it was unlocked. It was my understanding that it was just a plug and play procedure. Does anyone know anything about this VCI number, or have any ideas on what I can do to get this Nav unit to work?

Any feedback would be appreciated!

Thanks!!

That is total BS, here is a little bit about VCI:

 

 

About VCI

A Vehicle Configuration Index (VCI) is a number representing

a valid combination of parts and systems built

in a vehicle, including optional equipment. GM Service

and Parts Operations uses VCI numbers to identify a

unique calibration or group of calibrations.

If the VIN of the vehicle is not part of the TIS data, or if

the vehicle has been reconfigured from its original build

specifications (such as changes in tire sizes and axle

ratios), you will need a VCI number to access the SPS

vehicle calibration files during reprogramming.

Note: Keep in mind that many calibrations for reconfiguring

vehicles (adding/changing options, such as fog lamps) are

selectable in SPS and a VCI number is not necessary. If the

VIN is not part of the TIS data that is currently loaded, a TIS

error message will state that the VIN is incorrect or a VCI number

is needed. If a VCI number is required, contact Technical

Service at 1-800-533-6127.

They were probably doing it wrong....VCI numbers are available from GM, unless those are on restriction as well
