Hey Anas!
The adapter only uses the microphone and will work just fine without any other OnStar equipment.
Meaning you could get an GM Microphone, Install it into none OnStar equipped H3 Hummer and it would work just fine.

Hi there,
First, I would like to thank you for the precious and highly valued website(its really meant a lot to me as a hummer h3 owner).
I was lloking forward to purchase the OnStar Microphone Adapter from your website but i was wondering if i can install it since it is not there in my car.
FYI:
I already bought Metra GMOS-04 Wiring Interface complete set which supports Onstar. As i am looking forward to purchase after market stereo in my local country(Saudi Arabia).
thank you.
