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.
I’m missing the cover for my Onstar opening in my headliner. I have the wiring but somehow when an aftermarket radio was installed, the cover was lost. Does your adapter have the cover?
Hey Rick!
I don’t have any of the Microphone Covers. I purchase a bunch on eBay for $10 shipped years ago when I was testing which I think is your best option. Otherwise, I would search for an H3 in a junkyard that has one as a backup. Although, currently on https://www.hummer4x4offroad.com/forum/showthread.php/15079-Parting-out-a-2006-H3 is H3 Hummer getting parted out.
I am wondering with this adapter, will the microphone be disabled for onstar? I have an aftermarket headunit and the PAC RP5 GM11 wiring kit which supports onstar. I don’t want to use the microphone that came with the radio. I’d like to use the onstar microphone, but I want to keep the functionality of onstar as well.
Hey Sean,
The OnStar Microphone doesn’t retain the OnStar functionality.
Was wondering when you will have more of the audio converter available and prices.
Hey Al! I actually have a bunch of them in stock right just been behind working on all the different projects right now.
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.
