Once I realized that I had hooked up the antenna connection to the steering wheel control connections on the back of the radio, it worked beautifully !!

Pros: Easy to use , brainless.

Cons: Same size as the plug in for the steering wheel controls on the radio I installed.

Written By Chase L, La Crosse, Wisconsin on Wednesday, April 29, 2015

Crutchfield Customer Review (What's this?)

There is not much to say about a piece of wire, but what I will say is worked great. The connections into both the headunit and the stock antenna were tight. The radio reception did not degrade, which is good.

Pros: Worked great!

Cons: None

Wrong fit for my vehicle

Written By George, Baltimore, MD on Wednesday, April 29, 2015

Crutchfield Customer Review (What's this?)

I purchased an in-dash double DIN receiver from Crutchfield for a 2010 Colorado. Crutchfield provided this antenna adapter at no cost as part of the purchase. Unfortunately, the adapter does not quite fit. I contacted technical support. They did not have a solution other than to say there was a note to remove the copper ring inside the adapter.

Pros: None

Cons: Not applicable for my vehicle. Locally purchased a Metra AW-ADGM adapter, which fit perfectly. It also was significantly shorter in length, another plus.

Written By Ihacker, Wi on Thursday, April 16, 2015

Crutchfield Customer Review (What's this?)

Nice adaptor. Was suggested by Crutchfield as an add on and was absolutely necessary. When I put in my new deck it took seconds to install. Only gripe is it's very long. I installed a media receiver so it was shorter and left a lot of space. Would have been tight with a CD player.

Pros: So easy to install

Cons: unneccessarily long.

Got this for free when I purchased a new Kenwood deck for my 2006 Silverado CC HD. Works as it should.
