  • Exact fit
This is the only way to go when installing an aftermarket radio in a 2014 Silverado. It is an extensive install with allot of wires to figure out how to tuck back into the dash, but it is truly a plug and play install. No cutting of wires required. I recommend going to their Youtube page and watch the excellent videos they have on there. ... show more

  • Great product, I am glad it is around! Installing an aftermarket system has never been better!
Worked as expected, very well made, OEM quality and style connectors. One thing is that my 2015 Tahoe is one of the ones without an HMI unit behind the glove box, so the supplied connector for the rear view camera interface had nowhere to go. Luckily when I called iData link support they knew which wires on the vehicle side harness were for the camera. They suggested soldering to these wires, I counter suggested de-pinning the supplied camera connector and moving those pins to the iDatalink side of the main harness connector. This worked, and I hope they update their instructions for this work around. ... show more

  • Perfect for My 2015 Silverado 1500
This works great for my 2015 Silverado 1500 and I even get added features in my Pioneer stereo that I didn't get with the OEM radio.
