Your best bet is waiting for the 2004 H2 with the Nav and getting one from GM to install

Dennis,
Do you have a part # for that Nav system?

Yes,
I'm in my Star Wars PJ's now, I'll give it to you when I get to the office in the morn.

Dennis,
Did you ever manage to get out of your jammies and rustle up that part # for me?
Do your jammies have are rear hatch and feet?

I needed a navigation system badly for work...so I did my own little retrofit job.

Drtyfn,

Since the 2004s are almost here, I'm waiting to see what the factory NAV system looks like. If it looks like it will work in a 2003, that is the system I am shooting for.

You might want to wait as well...

Klaus,
Actually I am waiting for the '04 Nav system. My radio is acting up again and I've been working on getting an upgrade for my inconvenience.

Well, I called Delphi and asked them about retrofitting their Integrated Navigation Radio (INR) to a 2003 H2. This is the unit:

Anyway... Bad news. I was told over the phone that this unit cannot be purchased separately, and that GM does not plan to retrofit this unit.

So unless the dealer is willing to try this on his own (GM won't help) I guess we are S.O.L.

Too bad - GM could sell a bunch of them...

Klaus,

I'll sell you mine. Couldn't wait for info that would never arrive.

Goin with a set up like White Beast.

Sorry about the Bull **** I fed you...They(dealership) fed it to me. And at the time, it tasted good.

Visa is still looking into reversing my charges but I might be holding the bag on this one.

Dennis,

I appreciate the offer... But since Dephi's attitude is "No, we are not interested" I can't see how I'd get the info I'd need to make it work. What a shame... I wish we could talk to an engineer instead of customer no-service.

Good luck on getting your money back. GM, Delphi, and the dealership should be ashamed of themselves on this one...

All,

The Delphi unit shown in the PDF is the exact same one that is currently found in the '03 Caddy Escalade.

The Caddy has the capability for a separate 6-cd changer and also includes XM radio as an option on the unit.

Guess we'll have to see if Hummer includes all of these features on the '04s or screws the pooch once again...
