New Head Unit Install Questions C6
I am getting ready to tackle my FIRST audio install on a 2008 base coupe with Bose and Onstar. Here is what I am installing:
Question is regarding installing the relay required for the GMOS-04. Where should I get the 12v contant power required for pin 87 on the relay. Do I need to run a new wire from the battery (if so any install techniques would be helpful)?
- Pioneer AVH-X5500BHS Axxess
- GMOS-04 Class II OnStar® Interface for Amplified Systems
- Axxess Metra ASWC-1 Universal Steering Wheel Control Interface with New Micro B Connector
- Metra 40-GM10 GM Antenna Adapter
- Metra 95-3304 Double DIN Installation Kit

I have a 3LT with multi-channel. I too am thinking of replacing my OEM radio.... But then next year new speakers and a sub. Question will the GMOS-04 Class be a waste of money if I intend on using a new amp eventually? Or would I always be able to use the GM bose amp even with new speakers....and then only get a amp for the Sub in the summer 2014.
