New NAV Install (Kenwood ddx-7025)

[Rene S. Nielsen]

Hi

I'm just about to get my first Hummer H2 (used 2004 model), in about 2 months.
I have bought the Kenwood NAV headunit (DDX-7025) same as DDX-7015 but different region code.

I know this have been answered before, but I can't find the thread.

I need 2 different things I think....
1)
I some kind of little "box" that will make my all the warning sounds keep working, when I remove the original radio.

2)
Some kind of "box" that will make the "remote" on the sterring wheel control my new Kenwood radio.


I really hope some of you here can help me. I'm from Denmark, and we don't have access to these kind of things, so I need to get them on the internet, and then have them shipped.

By the way, We don't have On-Star so I don't need that to continue woorking.

Best Regards
Rene

PS. This really is a great forum.
