Verified employee purchase (What's this?)

Not much to it really, but it works perfectly to insert my Sirius player into the antenna input, since my truck doesn't have an Aux In and sirius hasn't offered a BT connected radio yet.

Pros: works great

Cons: its a little long

Fits great !

William from Valparaiso, FL on 2/22/2009

2006 MINI Cooper

Verified customer (What's this?)
Verified employee purchase (What's this?)

This adapter worked perfectly on my 2006 Mini Cooper where I was inserting an off the shelf Aux Input adapter in line with the antenna input to allow the use of an Ipod or XM radio through the factory radio. However, if doing anything similar to this, you will need both male and female adapters listed. Overall, another great product.

Verified employee purchase (What's this?)

Although a bit expensive, this adapter was necessary to get the FM antenna to work in the Volkswagen. It fit and is working fine. Without a direct connect, the "over-the-air" FM output did not work well -- required changing FM stations frequently.

Satellite install

Verified customer (What's this?)
Verified employee purchase (What's this?)

I received a Sirius satellite receiver for my new Nitro and needed a few parts to install it to make it look as professional as possible. A call to a Cruchfield's knowledgable tech support and I ordered the antenna parts I needed. Crutchfield has the BEST TECH Support/Sales people anywhere, the right part the first time every time. That's why I use Crutchfield for all my audio needs. Thanks

A
I need to test the antenna on my 07 Porsche Cayman. I think the current design (booster, windshield antenna) isn't working so I'm going to connect a normal vehicle antenna directly to the radio and if the radio gets reception (which it barely does now), I'll keep it. If not, then I'll purchase a new head unit. The Porsche unit is terrible, including the CD player. [ marc  May 22, 2016 ]
A
New truck, needed adapter to install my Sirius radio. [ Christopher  Apr 16, 2016 ]
