hummer17,
We were going to undertake the exact install procedure that you outlined, but GM does not list or sell the Escalade factory installed in-dash 6 disc changer. We inquired about it to our GM rep and he said that the GM computer doesn't list it or allow the sale of it.
They do list the 03 Silverado mirror with the integrated OnStar buttons and compass.
Sorry to be the bearer of bad news.
I guess we will all have to go aftermarket for the 6-disc changer with that new adapter they have out.
What I really wanted to do was install XM, CD changer and relocate the OnStar from the dash to the mirror and then program it all together with our GM Tech II. That way, we can have all the toys in the H2!
