2004 Nav Question?

[Klaus]

Kidzbox,

How many characters do you get for the song and artist? XM broadcasts 16 characters for each.

You can reprogram the VIN lockout with a EPROM Burner and a cable extension! You can also allow it to see both in a ghosting mode with the new code rewritten to check 2 locations!

Adding the Factory XM is not an option, as GM does not sell the digital tuner as a part.

Hey, Klaus. What about buying a factory 6 disc CD with XM already installed? GM is selling that unit in quite a number of trucks now. My wife has one in her '03 Tahoe. If one could be found, could you just plug it in and install an antenna on the roof?

We have added the 2004 NAV system to several 2003's but seem to have problems with some of the first units produced. In fact we have had problems with all of the H2's that were within the first 30 serial numbers (a total of 6 is what we have attempted the conversion on) is thier a inside tech guy that can explain the wiring harness change that occured on the first day after the pilot run. Is it something we can convert those original ones to. We actually have the first unit to roll of the line in to be converted!
PLEASE HELP!

I agree with Hummer Man(ic)

Pushrod,

The problem is that the XM Radio Module (Digital Tuner) is a completely separate box from the head unit. It is usually mounted in the dash behind the glove box, out of sight.

This box cannot be bought as a part, as GM has it on parts restriction. Also, it locks itself to the VIN number of the vehicle it is installed in, and will display "Locked" on the radio display if moved to another vehicle. Dealers cannot unlock the XM Digital Tuner Box. They must send it in to GM/Delphi for a replacement if there is a problem with it. Therefore, a used part is not an option, either.

Sorry...
