Any one know exactly what Scoshe and/or American International car stereo intall kit will work for a 2002 Pontiac Bonneville with Onstar, and a monsoon Radio system stock.

I have looked and it appears that Metra is the only company that has one for it. I don't like metra or Axxess because i lose the ability to adjust the onstar volume on the fly, and the chime volume with out having to take to radio out of the car. I like the idea that i still have control of at least my onstar. I would like to have it if someone is talking and i can't hear them i would like to turn it up with the radio or the volume on the steering wheel. Can someone help me with this?? I would so appreciate it.


If there is a nother company that would have what i am looking for please let me know....

as far as i know Metra/Axxess & PAC are the only two that have modules for our cars with the doc n lock harness

the question is how often do you use the phone/onstar?

im running the GMOS-09 in my GXP and it works great for me, but again, i barely use the build in phone and onstar
