Description

We at Metra always strive to listen to our customers. You have told us to do a better job at telling the Metra sto ry. For over 70 years, Metra has maintained its cutting edge by paying attention to our marketplace and innovating products to fit the needs of the installer. We are the "Installer's Choice" because we are installers. We design our products to be easy to use and easy on the eyes. If you can see a Metra product, then we haven't done our job. Metra Turbokits are designed to be heard but not seen. This means that our fit and finish is the best in the business. Why trust your installation to a shoddy and time consuming kit? Our GSXL Turbowires are designed with the same philosophy in mind. Their longer length for ease of installation and thicker OEM cables with OEM connectors make for a mighty install, with no down time on returns or angry customers.

    • Worked perfectly! And a note on the blue wire...
Style: 40-NI12 Pattern Name: Adapter
Worked great! A word on installation though - some people say the blue wire is used to activate the amplifier for the window antenna. That's not true. The blue wire on this harness is for the speed sensor, i.e., the radio component that turns the volume up when you go faster. The blue/white wire on the actual radio wiring harness is what is used for the antenna amp power. ... show more

    • Does what it should. Easy install, great price.
Style: 40-GM10 Pattern Name: Adapter
This antenna adapter worked exactly as it should. General motors has a weird size on their antenna plug so you need this adapter in order to install an aftermarket radio. It is very easy to install as it’s simply just plugs into both the new head unit and the factory antenna. I don’t believe the sound quality plays a part here as this is merely an adapter for radio reception. It does as it should. As for Sheerness, the adapter is well built and should last forever. ... show more

    • Perfect For My 2003 Trailblazer LTZ
Style: 40-GM10 Pattern Name: Adapter
I bought a Boss replacement stereo to replace the original stock unit in my 2003 Chevrolet Trailblazer LTZ. I soon realized that the stock antenna plug in the car is a mini version as opposed to the full-sized Motorola plugs on most stereos, so the LTZ's antenna cable would not plug into the Boss antenna input This adapter is exactly what you need to correct this. My only concern was that the stock plug didn't feel quite tight enough in the adapter, so I ended up wrapping a bit of black electrical tape around the area where it plugged into the adapter just to have a little more assurance. But beyond that, this thing works exactly as it is meant to. ... show more

    • Perfect Fit
Style: 40-HD10 Pattern Name: Adapter
You must order this antenna adapter if you are doing your own installation. You must also connect the blue wire in Honda applications. The blue wire is for power antenna. This does not mean mechanical power antenna that goes up and down, this means amplified antenna. These types of the antennas are amplified because these Hondas use shark fin styled antennas. ... show more

    • Simple adapter allows aftermarket radio in GM cars.
Style: 40-GM10 Pattern Name: Adapter
GM radios have a smaller diameter antenna jack than aftermarket radios. This is a cheap, easy solution to making your existing antenna cable fit in your new radio.

    • HINT: Make sure to connect the second blue wire
Style: 40-HD10 Pattern Name: Adapter
This kit works fine. But there are NO INSTRUCTIONS AT ALL with it, and there is a second blue wire attached to the connector with no indication as to what it does or where it should be connected. On my 2012 Honda Ridgeline, this blue wire MUST be connected to the Remote Out line from your head unit (the wire that remotely turns on external amplifiers or controls power antennas). Although it isn't at all clear from the lack of instructions, my Honda Ridgeline has an antenna pre-amplifier that needs power from the head unit; otherwise reception will be horrible. So if you didn't connect this line and your radio reception is unacceptable or worse than with the original factory unit, do some research to see if your Honda has an antenna pre-amp that needs to be powered through this wire. ... show more

    • Worked perfectly
Style: 40-GM10 Pattern Name: Adapter
I needed this to do an aftermarket install in my 2003 Silverado, and if you done it, you know that you need this mini-to-standard antenna adapter for most aftermarket radios. I plugged it in on both sides and it it worked great. I actually like having a little extension on the antenna so it's easier to do the next install if it happens again. The antenna works, the signal is good, so this cable gets a thumbs up from me. ... show more
