2004 Nav System Challenge

[hummer17]

Ok, here is a challenge:

Since GM couldn't get it right, for those with the 2004 H2 with the Nav system...

Try getting the CD changer unit from a Caddy Escalade (03 should work), it should fit exactly where the OnStar system is currently located.

Then, see if there is any way to interface it with the Nav system. There should be as this is EXACTLY the same Nav system as is found in the '03 Caddy Escalade which has a 6 CD changer.

If you really want to be enterprising, see if you can get your hands on the rear-view mirror with the On-Star buttons from a Caddy or any other GM for that matter. This way when you remove the H2 OnStar to put the CD-Changer in its place you'll still have the buttons (I believe there should be a way to interface this as well).

With all the brain and tinkering power on this board it seems that this should be easily done and prove to be a huge upgrade. Heck, if you can figure it out, you could probably make a kit out of it and sell it to other 2004 H2 owners.

Be brave and post your results here.

Please no comments on using aftermarket Navs on this thread - not the point - trying to go OEM and improve upon GM's slip-up...
