This item is so simple yet such a necessity. Easily installs and works like a dream.

Pros: Right angle end that goes into the radio makes install and routing easy and low profile.

Cons: A little long could be shorter.

why is this needed

Written By mvedwar, South Carolina on Monday, June 15, 2015

Crutchfield Customer Review (What's this?)

I have a GM car and this wasn't even close to fitting. Length was fine but the female end was too small for my existing antenna. Luckily my cord was already long enough to reach the radio so I threw this out.

Pros: None

Cons: Did not fit even though this was the recommended adaptor

Easy to install

Written By James, Lumberton, NJ on Thursday, June 11, 2015

Easy to install. It plugs into the aftermarket unit on one side and the antenna connector plugs into the other side.

Written By KYWes, Kentucky on Sunday, May 31, 2015

Crutchfield Customer Review (What's this?)

GM uses a smaller antenna connector than most other brand of car and it is smaller than more car stereos have. This adapter is necessary to mate the vehicle's antenna to the head unit. The antenna adapter I received was of high quality and fit just like it is supposed to.

Pros: Convenience, fit, functionality

Cons: None
