Review on Metra GMOS OnStar Interface Systems by Luis Norman

Revainrating 5 out of 5

Works as it should!

I spent extra time soldering each connection so my install took a bit longer. Other than that, this kit worked well for my application. I have a 2004 Chevy Avalanche, unfortunately I did not purchase a matching steering wheel control kit. If you're on the same machine as me, please don't repeat my mistake. The kit I am reviewing had everything that was advertised and worked well. I would use this brand again and happily do so.

Pros
  • Interface for replacing the factory radio with an aftermarket unit in amplified GM vehicles with Premium or Bose audio systems. Maintains full OnStar system functionality with adjustable volume.
Cons
  • Not sure
