Hi guys, need some help with an aftermarket stereo.

Looking to replace the double din monsoon radio with a Pioneer. My H3 is a South African model, no ONSTAR.
I'd like to retain door chimes and rear view camera, the adapters mentioned on the thread below are specifically made for ONSTAR.

Can anyone recommend an adapter that serves this purpose?
I don't want to sacrifice audio clarity.

Appreciate any input from you guys.

I replaced mine with a double DIN Pioneer AVIC & I also have SAF build (in Australia)My installer said there is 2 types of adaptor so he guessed which one it would be & he picked the wrong one, returned it & ordered the right one.

If I was to do again I would order both & save the guesswork, then try to return the one that doesn't work.

To keep the factory amp wiring, chimes and RAP for a US truck, you'd need the Metra GMOS-04 harness. I advise that you call or email Metra with your VIN to verify that it's the correct harness for your SA truck (Maybe a SA distributor?). There are other makers, but I got excellent tech support from Metra when I had to work through an older iPod installation that was causing issues when I installed a Pioneer AppRadio.

I just put a 4100NEX Pioneer in my 2008 H3 Alpha Adventure/lux package truck. I eliminated the On-Star (kind of inadvertantly, but I love not having my vehicle ding at me for low tire pressure, seat belts, etc).... I used the GMOS-01, the only caveat is you have to run the amp power wire around the GMOS-01 adapter/controller from the stereo directly to the truck's wiring. The GMOS-01 has the wires necessary in the plug. I bought both adapters, thinking that (after I bought the 01) that the 04 was the right one. I compared both....

only downside is now I hear how much the pillar mounted tweeters suck...
