Installing the 2004 GM DVD Navigation System in a 2003 Hummer H2


Parts:

DVD Navigation Radio: 15204335 $1730.00
GPS Antenna: 15207447 $ 54.30
DVD Navigation Disc: 15105609 $ 220.13

Summary:

Notice – I do not yet have a DVD Navigation Disc, so I cannot verify that the Navigation function is operational.

I installed a new unit purchased directly from a GM dealer. Other than needing to modify the GPS antenna bracket to mount it under the dash pad, this was a plug and play swap. No dealer programming was necessary!

Details

The connectors on the 6 CD changer radio are exactly the same as the NAV unit. The NAV unit has an additional plug for the GPS antenna that mounts in the dash.

Finding a dealer that could sell me the NAV unit was a real struggle. Every dealer that I called tried to enter the part number in their computer, and came up empty – Meaning that they could not order the part. Then I called a local GMC dealer. He also could not order the unit. However – He went one step further for me. He entered the part number in his national parts locator, a system dealers use to find where parts are in stock at other dealerships. A Cadillac dealer in California had 5 in stock.

I immediately called the dealership, Cadillac of Menlo Park, (650) 688-1543, and talked to Mike in parts. He said that they regularly swapped out the units in Escalades. All 5 units he had in stock were sold, so I had him order me a unit.

He called me when the unit shipped, and stated he ordered 12 more units. I don’t know how this dealership can get these units when no one else can – But they can get them.

I ordered the GPS antenna, and later the Disc from GMPartsDirect.com. I should have the Disc in the next few days.

The radio, CD player, OnStar, rear seat controls, and steering wheel controls all work perfectly. As I stated above, I cannot test the NAV function until my DVD disc arrives. However, I have no reason to believe there will be any problems.

I have taken 90 digital photos during my install, and will work on a write-up.
