Thats what I'm using in my 07 Trail Blazer SS! You will need Steering wheel Control interface too if you have Steering wheel controls.

Did you use a steering wheel interface too???? What wire did you hook to? Did you have to go to a plug under the steering wheel or is it in the main wire harness for the stock radio? Thanks Ross

Thanks Mark Mute got me to thinking, when I saw that we move the Mute pin to bypass! How will onstar mute the system? Great info! Thanks again!

THANK YOU SO MUCH Necro!!!! Just what I needed to know! WOW!~ YOU ARE A PEACH! You do math like you give advice! Not very well! I think 6 hours is ok to bump a question on a fast moving forum like this! When you’re trying to do an install that night! Sorry to bug you Mr.! Maybe just leave it be if you have negative stuff to say Boy, you make this a fun place to hang out!

Anyone?????

Hello All This is my first post here! GREAT SITE!!!! I have been installinig car audio for myself and friends for about 15 years. I have a 07 Trailblazer SS thats I'm getting ready to install my D3 in! I have 2 questions that I did a search on but could not find anything! 1) With the bypass mod and the mute Pin/wire moved and grounded. Will my onstar/phone still mute the system without a mute wire hooked up? Or do I need to find a new pin/wire to replace the old mute wire I used to do the bypass? In outer words have the mute wire (from the D3) hooked into the mute port
