I have an 07 H3 with the factory monsoon system. I have purchased the Pioneer Avic-Z2 and want to retain the factory monsoon speaker and Onstar functions. I was wondering if anyone could reccomend the exact Digistar for this system. I have contacted Soundgate with no reply to my inquiry may have to call them. I was wanting to know the exact part number to retain my factory onstar and which one is compatible with the monsoon system. Thanks

 

Curiously I have the same question, but different system. I have a base with the plainest radio you can buy...want to put in a double-din nav/dvd head unit...maybe a JVC or Kenwood. I'm thinking that the person who knows the answer to the first question might know mine, too

 

So what is the answer??

 

I actually went with the PAC OS-2. I got it without the door chime module. It works great. I also had a Pioneer Avic-Z2 installed. It is a wonderful system. I have my onstar and the built in phone now retained.
