Review on πŸš— Metra 40-GM10 GM Vehicle Antenna Adapter by Rob Dixon

Revainrating 5 out of 5

Does what it should. Easy installation, great price.

This antenna adapter worked exactly as it should. General Motors has an odd antenna plug size, so you'll need this adapter to install an aftermarket radio. It is very easy to install as it just plugs into both the new head unit and the factory antenna. I don't think the sound quality plays a role here, since it's just an adapter for radio reception. do it right As for sheerness, the adapter is well built and should last forever.

Pros
  • GM factory antenna with "No Barb" or "Barbine" mini connector for secondary radio
Cons
  • Secret
