Doesn't work on 2007 Pontiac G5

Bought this as a cheap alternative to change my in car stereo on my 2007 Pontiac G5. This adapter clearly doesn't fit. Not worth it to ship it back as I'd break even.

Metra harnesses #1 again

I love using the Metra harnesses. Metra is the top of their game.

works like a champ

If ya don't really care about the ding ding from your car this is a cheap way to get an aftermarket radio in your ride.

Super Buy

This product arrived on time and is easy to install. Very impressed. Fit right into my car with no problem. I would recommend this product

Easy for all

every wire matched up to the wires from my stereo so it was just splicing and plugging the stereo wiring harness into the vehicle wiring harness and that was it!

Worked perfectly

Perfect fit for girlfriend's 2008 vibe. Wiring was all correct and plug fit properly.

great harness

this harness worked great. just plug and play. good job Sonic

Nice

Works great with my grand prix makes installation way easier no need to cut wires

Works perfect as it should!

I have an 2004 Colorado, I did have a a fancy chime retention/computer harness and kept having lots of weird electrical issues. I replaced the unit w/ this unit and have had no more issues. Should have went this route in the first place.

good

Great simple harness. The fact that it was free with radio purchase is great too.

works great

Easy to install, great tech at Sonic turning me on to this part.

Great

It works great. I am very pleased with the product.

excellent

Worked as advertized. Was the correct adapter.

Metra 70-2003

Quick shipping. Product easy to use and install and works perfectly.

Very easy to use

I found this extremely easy to use and it was very helpful for simplifying my installation into a 2003 Toyota Matrix

did alright.

I put this in an 03 silverado but when I installed it everything matched except the power wrote so I had to wow it into a fuse.

easy

Worked like a charm. Wires all matched up as they should

Wrong Harness

Needed a harness for a 2004 LeSabre. Wrong one. Needed Scosche GM07B since it has the GM Dock and Lock system.
Be sure to check to see if u have the Dock and Lock in your car before ordering.

Needed a part

I needed a new wire harness to replace a bad wire job on my daughters car. this did a great job for us.

Perfect for pontiac vibe 2008 antenna adaption

This fit and adapted girlfriend's antenna plug on 2008 vibe to stnadard aftermarket size.

Works well

Made connectivity very easy. No need to cut into existing car harness.

Works well

For the price it works well on my '06 Colorado. Required for my install. Radio reception on my HU is not as good as my factory, but I blame that on the HU.

Perfect Fit

Perfect fit for Corvette. Very strong and clear signal

great product

this is a very easy install, works like sonic advertise. read the instructions and everything is up and running. Sonic is great,

Perfect fit

Ordered this for my 04 Silverado wasn't sure it would work because all the forums stated I would need a $100 adapter, thought I would try it for 5$ and it worked great I did lose my chimes but having a aftermarket deck in my Chevy is far more important to me than a worthless seat belt chime

Great value

Great product, would recommend this product to anyone. Fit perfectly.

Great Busines to Deal With!

We have had no issues with Sonic Electronix until recently. We had moved from my previous address 3 years back and UPS not Sonic Electronix shipped the item to the old address rather than the current address. Having a conversation with Sonic Electronix quickly resent me the package and the situation was under control. Sonic Electronix has been good business people and highly recommend them to business small or large.

great product

this product made hooking up my antenna easy and fast

Not required for my 2007 Toyota

Although this part was recommended as needed for my 2007 Toyota Matrix, it is not needed as the antenna plug on the car is the correct size for the unit - and therefore too large to go into the female end of this. I am debating returning it, but it has been opened and cost $5.00

Still have

Didn't use this, already have one installed, will keep for future use

By David on December 24, 2015 Verified purchase

Works

Bought it for a 2005 Silverado which it doesn't work with completely. The radio and speakers work but you lose the door chime and a few other small features I never really cared for anyway. For me, it was a perfect purchase.

Good product

No problems what so ever just plug and play and ready to go

Metra 70-2003

Good product. Fit good. Works as it should. I would recommend this product to a friend.

Metra harness

I spent time searching for this adapter & am glad I did. I bought an aftermarket radio that needed a specific part & this is it. Do your research & metra is a recognized brand.

Great product!

Exact fit for my aftermarket radio. Could not have installed without this product.

By Bryan on April 3, 2018 Verified purchase

worked for me

I bought this to install a radio and EQ in my 82 Trans Am. With a little cutting it worked out fine, it has the cutouts I needed they just dont make one for the 82.

Works well

This worked for me and the radio station I listen to have no static.

Solid adapter

I've always loved metra adapters. They fit tight and have a good quality finish.

Saves you $ if your truck isn't Bose or if you don't care about onstar.

I've been professionally installing for almost 20 years and Metra makes the best parts on the market.

By Benjamin on March 27, 2016 Verified purchase

Great Deal

An excellent recommendation for the car stereo that I had purchased from Sonic Electronix...

By Miguel on February 29, 2020 Verified purchase

Ordered on accident.

I ordered this by mistake and the company saw that I didn't need it for my vehicle and took it of my order. This is a great company!
