Cool but Not Necessary

This is a cool gadget. However, all I had to do was throw away that Sirius FM transmitter, and the signal transmitted fine to the radio. You only need this if you live in a big city, and there are no static free radio stations. Then it would be a must-need.

Metra 40-CR30 Pioneer Inno XM Adapter

Hello, I purchased the Metra 40-CR30 Pioneer Inno XM Adapter for my Ford Flex with Navagation. It was a direct fit and worked Awesome. It allows crystal clear reception through my portable XM Player through my factory system with less static and interference on the radio. I highly recommend this adapter!

Works Great.

I have a 2013 Ford F-150 and this product enabled me to add HD digital radio to the factory system and use the factory antenna. Very easy to install.

Nice Product

Received Sirius Radio as a gift for an older vehicle. The adapter made the installation very simple and my system works great.

Exactly what I needed

Needed the antenna converter, and they had exactly what I wanted, and not at the inflated auto store prices. Great price, excellent quality and quick shipping. Was able to attach external HD radio to my Dodge Truck.

Did what it said!

This is the ideal product to add an aftermarket Sirius Radio to your Jeep Grand Cherokee. Easy installation and worked perfect the first time. This is your solution to the proprietary plugs on the back of your factory radio.

Good price

Perfect for install of FM modulator. Adapts both ends. Better priced than buying both pieces separately. Can't loose.

Perfect for my Focus

I had bought a cheap antenna adapter that really didn't work. I purchased this one and now I'm picking up tons of stations!
