Didn't work for me

December 20, 2011

I tried to install this in a 1993 GMC Sonoma (S15). The problem was the stereo was too long. Mind you this was a standard size radio, a Pioneer DEH-P4900ib. I even tried another radio I had but it was the same size. The total length with wires attached (and bent to the side) is about 7 inches, about 1 inch too much. I guess I'll have to try the scosche now since it juts out a bit more. Otherwise the kit looks nice and seems to be made well it's too bad I can't use it.

Great radio

October 4, 2014

Works great in the car. For the price it is worth it.
Just double check on the mounting bracket. The one the website recommended for my car was wrong. Actually needed the other one they had. They sent the second one out to me and everything worked great.

Radio install kit

September 13, 2012

This is the second of 3 kits I have ordered from Sonic. They have all fit well and were a great value. This one fit just right in my 1996 Bonneville.

Ogden, UT

nice unit clean looking install

February 12, 2015

Really makes for a good looking install. Instructions are a bit lacking and I used real nuts and bolts to hold it together along with a little glue. Design could have been better but being that it is universal and free can't complain.

Metra 9900

October 29, 2013

I got this for my 02 Silverado, reviews weren't too good,,but I decided to try anyway. Glad I did, perfect fit and easy installation if you're not an idiot. Pocket was enough to hold s3 and remote. Differently recommend.

2002 Camaro required modification..

June 22, 2014

It wasn't very good for my model, which was included for it I ended up cutting tabs off and getting it to work. Other than that it is a nice little kit

This is a time saver!!!

November 1, 2011

Pros-Really made the install simple. Con- Fit/finish in a bit off from OEM. A must when going 1.5 din to single din. Pocket comes in very handy, however it would have been better if it had a larger opening. Great to hold remote, usb and aux cables, however it's not even tall enough to fit an Iphone 3gs without the case. Made the install that much easier. Multiple configurations make adjustable to your preferences (pocket on top or below unit). Made of a durable material. Only real complaint is upon installing the radio sleeve and pressing the locking tabs outward, the tabs closest to the pocket cannot fully extend and the sleeve is only secured from 3 sides.
