Ok So I am thinking about adding this to my 07 H3. I have the Base sound system with a single disc CD player. I am wanting to install this. http://www.sonystyle.com/webapp/wcs/...52921666073658
Will it work. What will I need for Onstar?

 

Any help?

 

I believe you need the gmos-1 to keep your onstar, chimes etc. I may be missing something here but I plan to update mine soon as well, I really like the touchscreens plus I want a back up camera.

 

Thank you. I want it for the backup camera as well. Do you like the system I picked out? What system are you looking at getting?

I also have a question about the Stealthbox Monsoon Sub. If I buy one without the Monsoon system can I still use it? Just as a sub?

 

I haven't picked out a touchscreen yet, still looking. Yeah the deck you picked out is nice!!! I don't know about the monsoon sub but assume you just have to run the wiring to it.
